Divergent - Veronica Roth This is one of those times when I liked the movie better than the book.

Heather K brought up some excellent points.
That said, I was able to enjoy the book much more than her, mostly because I've read it without thinking so much. Which is probably because the book and the movie are basically the same. The movie is a fun way to spend an idle hour or two if you have nothing better to do, but I can't bring myself to say the book was worth the two days it took to read it.
