I picked up these books throughout last year, reading the first 9 (aka, finishing Winter's Heart), but after that I just couldn't be bothered to pick up the next book even though I had promised myself to get through the series just for the sake of it. I don't know why I just can't seem to enjoy them because my reading habits seem to match a lot of you guys that post here. Might be I just overloaded by reading the books without taking breaks from the series. The books feel quite more similar to each other compared to say the Malazan books (in my opinion), because I didn't have a problem churning through those.
Another reason is just the overall slow-down in the series. Much like I feel with GRRMs last two books (that, while cool, are dragging on and of much lower quality than his previous three) there simply is so little happening. Just looking at what the "gang" accomplished in the first three books and then you see what they actually do in those that follow it just feels slow, and not in a good way, but slow as in soap opera style where you can skip a weeks worth of episodes and find that they are still in the same room talking about the same things (I exaggerate I know). It's not that you have to churn your story / plot onwards at every turn, but there has to be a sense of progression - be it through dialogue, description or action. Malazan I think is a prime example of this where you don't have to have much action taking place to advance your story.
That said, I will be picking up the series for the last few books, I have high hopes for the Sanderson written ones since I enjoyed his Mistborn series, and if he treats the characters well and actually manages to advance the story it could turn out to be worth it.
Also, I fully believe that in a realistic world, every bloody Aes Sedai would wake up with a) their throat cut or
a fine collar after their first day as an "advisor" to anyone... At more than one point (in the latter few books) I was just hoping that Rand would shove his sword through Egwene in one of his temper tantrums (it could be blamed on Lews Therin or something I don't care), that would have made things pick up a bit at least.
