I haven't seen any of the movies, but I've heard that there not good either. I've noticed it's mostly a younger crowd that like the movies. It must be that they just like anything vampire themed, and maybe a lot have read the books, and want to see the screen version. My friends' teenage daughter read the books and has seen the movies.
The movie is kind of bleak the way the vampires on it sparkle instead of bursting into flames when come to contact with sunlight and I am being truthful I like to watch it I think mainly cause of Taylor Lautner he is a handsome devil LOL :)
