I like all the all the characters but there are some that get on my nerves more than other.
Egwene starting in towers of midnight: She's written very well, politicians just tend to annoy me.
Elayne: Seems like an adolescent trying to be a grown up the whole book. She's constantly doing irrational often fruitless things to get herself captured and other people hurt or killed. She's a pushy and annoying political figure.
Most Aes Sedai: There a bunch of squabbling hens that don't get anything done. Accurate description?
Perrin in towers of midnight: I feel like a good majority of this book was Perrins chapter and frankly I was just sick of chapter after chapter being Perrin chapters when I just wanted to kind of read about how Rand was being a bad ass.
My favorite character through out the series was Rand. I don't think I really need to explain my reasoning, he's just a bad ass out to save the universe.
