Aww, damn, after typing the whole post I probably should preface it with 'yeah, I get your issues with it, I had them as well, though perhaps not as strongly, because I kept reading anyway'. Basically, a lot of your issues, especially the smaller ones, are either adressed later in-story or can be explained by, uh, thinking about it?
Also, this post may or may not make me look like a rabid fan of Cal Leandros

I am not. Not rabid, anyway. But I love the books for what they do well and don't mind the faults.
So, here goes.. Also, further down I adress the spoilers for the first three books you mentioned, and those for book four I put in tags, just in case.
Right, as I already have mentioned elsewhere, I have read this series up to
Roadkill, so I can address some of the things you said, but I will also say that seeing as you seem to dislike so much about it even after book three, this may just not be your cup of tea.
Personally, I love this series and that while I actually had A LOT of the same issues with it as you do. What kept me reading were those parts that did some interesting things with the genre and I have found that patience is the way to go. I love it. I love how I keep thinking 'meh, this is stupid' and then the books go and address that very same thing. But it takes some time. There's three things I have found to be the case with these books:
1. They're primarily character-, not plot-driven.
2. The very well done character development works it's magic mostly across several books.
3. The plot is very focused on what's the deal of the day in each book.
So far, each book has been more or less self-contained, while the characterisation stretches from book to book to become more intricate. I rolled my eyes at Nico for the first couple of books and I freaking prayed he'd boot Promise out, but they both get some serious development in book 4, similarly to what Robin got in book 3, except better written, because let's face it, that seemed a bit disconnected. Rafferty & Catcher get the same treatment in book 5, so here's were you look when you want to know how Catcher got trapped in a wolf-form. As mentioned, it's pretty focused, so to find out stuff, one has to wait for the book in question. One could argue whether that's a good or bad thing, but since I'm good with that, I frakly don't care.
At the same time, I enjoy seeing how each character changes based on what's gone before from book to book, and whoever claims that the tone of Cal's point of view does not change is clearly blind, deaf and also dead inside.
That said, yes, Nico is over-the-top. Hell, pretty much everyone is over-the-top. Promise is the prettiest, Cal is the angriest, Robin is the horniest, Rafferty is the best healer, one could go on endlessly. It's just that kind of series. One either lives with it or not. I've read stuff before where evereyone's the best and prettiest and everything but the story somehow seemed to want to hide that and turned into a convoluted mess, so I actually prefer it here where the story revels in it's over-the-top-ness and gets on with business.
As to the villains..

Book 1 the villains are the Auphe who are like the ultimate predators who are feared by everybody. This is ok, I guess, due to Cal's history and everything, but having Cal kill his father offscreen and arguably off-plot and then letting Niko fight Auphe on a more or less equal basis, I mean no Auphe could win one on one, It was pure numbers all the time, it just seemd off.
I agree, the Auphe are played up as a bit too ultimate evulz for my liking as well. Then again, one could argue that that's the point. They may be the ultimate evil of times past, but now they're down on their luck and all that keeps everyone from zerg-rushing them into oblivion is their reputation. Why else would they need to stage all that crap in book 1? Why else would they need to go to the lengths of having a half-human/half-Auphe child produced? They're desperate. And even more so since in book 1 [spoiler for book 4 ahead]..
Puts the 'Cal needs to get laid' stuff in books 3 in a somewhat new light, no? Irony is a bitch.

Book 2 the villain is a Puck. The ultimate, original, deadliest Puck, who almost cannot be killed. Cal takes him out by chucking him through a gateway.
Hob may be the original puck (the way Robin puts is that Hob is the original madman, and the oldest puck around, but none of them seem sure who was actually the original
puck, but I never got the impression he was invincible or anything, just really, really tough - like, say, a whole bunch of people running around in these books. If he was, he'd not need the crown thingie, right? Also, I was more pissed about Cal getting to use his gates instead of Hob getting thrown through one. I expect news on how Hob fared at some point down the road. That said, as soon as I started to get annoyed by Cal using gates left right and centre, Thurman subverts it again. This made me learn to trust her.

Book 3 its a murderous Redcap, and of course the deadliest most murderous Redcap, who is almost impervious to physical harm. Nobody even tried to explain how his ashes reanimated in the first place.
Yeah, I agree, the Redcap business seems somewhat contrived. I'd rate the third book as the weakest so far. Personally, it gave me enough other good stuff to be fine with that. However, didn't Wahanket reanimate Sawney? Seemed enough of an explanation to me. Wahanket clearly is some kind of egyptian mojo magic wazoo and according to Robin probably not even human. He reanimates dead things for shits and giggles. Sure, we don't know
how, but we also follow Cal's point of view, so how would we?

My main point is that all the villains are at the ultimate level. It strains the believability factor. Which brings us to believability.
Third issue: Believability: This mainly became an issue in the third book but its present in the second book as well. Niko and Cal go around carrying and using swords, guns with explosive rounds etc and literally nobody notices. They always seem to be able to leave just before the police arrive. In book 3 the revenants are taking students from a university campus. There are live eyewitnesses. The group run in, run out and nobody notices them? I mean this is post 9/11 New York! CCTV surveillance? The Redcap and his crew killed at least 6 non-homeless peopel including a famiy complete with kid. The cops would have inundated the area. There would have been a building by building search of the campus. None of this happens.
So yeah, the villains ARE over-the-top. But so are the good guys
As to the believability.. Well, you either buy it or you don't. Believability is not exactly the focus of the series. For what it's worth, I think that within it's own universe the world is quite coherent and believable. If you're going to complain that people carry weapons around, might as well complain that there are mummies, a valkyrie heading the board of curators, revenants running around everywhere, and werewolves out in public.

Then theres the factor that a family of man-eating mud monsters lives in Central Park. The horrific implications of this are explained away by saying that they only eat muggers and other criminals. Ummm. how exactly do they know that? The Boggles seem to be extremely ferocious hunters. In the 3rd book, after being seriously injured by the Redcap the mother Boggles main problem was she couldn't hunt. It wasn't a food procurement problem, her kids could get the food, but she just liked hunting. You know, killing for joy and all. And these creatures are supposed to only eat criminals?
Cal assumes they eat only criminals and iirc he doesn't believe that himself. Which leads us to another point which ties in to the above.. Believability and what I mentioned earlier about the plot being focused to the matter at hand. Cal actually starts wondering in book 3 about, say, the corpses the found hanging from trees at the start of book 3. Then there's the crashing warehouse in book 1. All the little things, the corpses they leave behind, like the dead students on campus, or the fact that none of it made the news.. Guess what? Along comes book 4 and..

Robins informants always trying to kill them....why did the mumy even do that? Because he was bored! And Cal gave him a gun as a present! Its never explained how how the sirrus got into the museum
Yeah, they do. Also, yeah, Cal remarks on that on more than one occasion. It's not like Thurman tries to pass it and hopes nobody notices. No, she adresses the issue head on, which is what I like about the series. It is aware of itself, and after five books, I expect more to come on that. Basically, though, it seemed logical to me. Robin's informants are mostly beings hat have lived for a very long time and have never been on the nice side of the character scale. Also, he has a whole bunch of informants, and we have met.. two? Or three, depending on how one counts, as Ishiah's on the opposite scale, if I may say so.

George is a strangely underutilised character who is either the Damsle in Distress or somebody for Cla to pine over.
Alright, I'll be honest, I loved how George's story got handled. I mean, you have this uber-talented psychic girl who's the main character's love interest, and she's sweet and nice and pretty and smells nice and she's wise and patient and just generally perfect, yes? Then she gets a damsel in distress plot-arc.. Holy fuck, I was ready to throw the books at the wall. But guess what? She's not actually a damsel in distress. She is a girl who gets kidnapped and being a psychic, she knows what will happen, so she calmly bides her time. She is so freaking stubborn that she insist on a relationship with Cal on her own terms and if he cannot accept the way she sees things in context of the whole universe - because, duh, he's been on the run all his life and all he asks for is a
little consideration of anything that's less than of universal importance - , well, touch luck, dear Cal. So she folds her hands and waits for Cal to 'get it', and yet she's the 'superior' one in that constellation. And what does Cal do? He slams the door in her face. I thought that was suberbly handled. It's a realistical portrayal of a relationship between two young people who are so vastly different in character that only work on both sides could make it work, but both are too caught up in their own realities to realise that and act in ways that reflect that. It also serves as an incentive for Cal to move on and grow. There's another exploration of an unlikely relationship later, with Robin and.. ah, not saying

But it goes in a wholly different direction while being handled with just as much understanding.

Frankly that whole Cal trying to get laid bit was just lame. I mean it was probably supposed be funny, but I found it rather sad and pathetic.
Cal is pathetic. He's an angry teenager (he IS mentally younger than physically) with trauma and lots of issues. I thought the 'Cal needs to get laid' quest served quite well to show that he has this idea of never wanting to sire a child and still get laid and is so stuck up on it, it's pathetic. So he really needed
something to show him he needed to relax some. That's probably why Robin dragged him to all those ridiculous.. acquaintances of his. Do you really think with all the people Robin fucks on a regular basis he wouldn't have found someone less ridiculous?

Then there are the annoying off-screen things I actually would have liked to see like how the Healers brother got turned into a wolf
See book 5.
I do, of course, have my own issues with the series, first and foremost the way it rehashes what's gone before and Cal's past every damn book, several times over. I get it, I've read the previous books, so get on with things, damn you! But for now the good things outweight the bad ones.
It also annoyed me a lot that there was no hint in book 1 that Rafferty and Catcher are..
Also, I think Cal is hilarious. I see how one can get tired of him, but it's just right up my alley, humour-wise
I have a few things to say about the problems of the first book, but this post is already waaaay too long.
