I re-watched it and the _______ {{spoiler but you'll know when you see it}} was over 3 minutes long. Very well done by the voice actress.
The whole thing had me feeling emotionally conflicted, too, because...
Fate/Stay Night/UBW (5-6) - Wow, Rin needs some aim-assisting magic to go with her crazy lasers (hereafter known as "Crazers").
And hey, there's Assassin, and there's Caster, we're meeting the whole gang! Look, there's Ri- huh? Assassin again? That's weird. I don't think there's anyone unaccounted for in the OP, either. Maybe Rider will stay a big mystery for a while, or maybe there really is 2 Assassins. It's not like any of the "rules" of this series ever mean anything

But seriously, don't Shiro and Sabre ever talk? Like, after he gets attacked by a Servant in the forest, he doesn't tell her about it later that day, so when she runs into another Assassin Servant she might think it is odd? She might get some advantage out of it? Nah, tactics are for wussies!
Oh well, I'm sure it'll be a fun fight.
You can really feel the pain of this sticking to the high school anime cliches though. Ooooh, what a surprise, the creepy bully kid in Shiro's class turns out to be a boss fight, what a shocker

Log Horizon s2 (6-7) - Episode 6 was interesting. I won't say much for spoilers' sake, but we've been waiting a long time to learn more about what happens... there.
Episode 7 was pretty boring though. Just more setup for the fight with evil Santa and a lot of vague mutterings about the Teachings that were ultimately pointless.
Things in the game changing to follow the rules of the real world more is an interesting idea, but after all the pseudo-mysteries from last season that weren't followed up on I'm not getting my hopes up that this will get much depth.
Shingeki no Bahamut (6.5) - A recap episode? After 6 episodes? Wuuuuuh?
Sword Art Online II (19) - Yay, Rosario arc. Kirito was getting a bit too "everything's coming up Milhouse" after GGO wrapped up - shifting main charactership to Asuna is already a lot more interesting than if they pulled out some new not-previously-mentioned drama on the Kirito side. Asuna's mom really is a nasty woman, isn't she?
It also needs to be said that SAO is absolutely nailing it with the OPs this season (though I really liked their season 1 OPs, too). The synchronized music and visual shift in the GGO OP with Kirito stepping out into the battle scenery in the latter part was really well done. I love the new song for the second OP of the season, and the visuals for the Caliber version were especially great - they made some really smart choices mixing the real life and VRMMO elements, showing the actual VRMMO bits like health bars and whatnot, and adding the Aincraid flashbacks as well. I think I actually prefer the Caliber to the Rosario one, but the Rosario one is still very, very good and I'm sure Rosario will grow on me once we get farther into it.
In contrast, I don't know why some people in comment sections are raving about the Shingeki no Bahamut OP. It is too screamo for my tastes, but even personal tastes aside it doesn't blend with the show or match any of the music in the show itself. Maybe those people are just really big Existenz fans.
