Psh. Harry Potter of course!

Twilight is...well, I wont go on my whole rant about it, but I WILL say the 2 biggest problems I have with it are these:
1) Bella's willingness to accept Edward's controlling personality
2) Bella's dependency on having a relationship

I wouldn't care so much if it weren't for the fact that those books are the bible for millions of American pre-teen and early teenage girls and they will likely base their real life relationships off of what they look up to--in this case, the Twilight series.
