I've finally finished the Twilight series! I read the last two books back to back - Eclipse and Breaking Dawn.
To be honest, I'm not a big fan. I don't really like the characters that much and the story is pretty simplistic. The books are just way too long, and I just got tired of reading the same character descriptions (yeah, I get it - Edward is cold!!)
I know a lot of people didn't like the way the series ended, but I thought Breaking Dawn was at least a bit more interesting than the first three. Still, like the others, it was just too long with not enough interesting things going on and characters that just kept doing and saying the same things over and over.
I've read many YA series, and most of them were far better as far as the writing, plotlines, character development, etc. The Vampire Academy series and Harry Potter for two.
