Normally I don't read books like this, but my girlfriend suggested this to me and I actually liked it. I do agree that the overall mood of the book is a bit angst and makes little attempt to resolve the teenage drama. But I do like the character relationships going on, especially in Twilight with Bella and Edward.
A little note, there is a movie
in development for Twilight. Catherine Hardwicke is scheduled for director, the same person to direct Lords of Dogtown and The Nativity Story. I don't know if Catherine is the right person, although Twilight does kinda fit her style of filmmaking if you can relate the story to Thirteen.
Personally, Hollywood brings ruin to the unique. And besides, I don't think Twilight can be adjusted to the formula of screenplay. After all there's so many details in Twilight that aren't usually expressed in movies.
