Just copying and pasting what I said about the Divergent movie in the weekend thread to here to avoid ruining it for people...
Honestly, I didn't love it. I thought the special effects sucked, the fight scenes were boring, and the setting/buildings/background was lame. I don't think I like Shailene Woodley as Tris. Four was really fun to look at for the 2.5 hours, though. There were things that were changed and cut out which I guess I understand has to happen with books to movies but it was still annoying. The friend that I went with hasn't read the books and she liked the movie a lot.
I was actually ok with Caleb but I expected Tori to be WAY more badass and ragey than she was in the movie. She was like a timid little sheep!
