I hate being "the book was better" guy, but damn they really missed it on this one. The first one minute was like the book after that it was completely different. If you didn't read the book you'll probably love it. I'm guessing that's where most of the 9/10 reviews are coming from. The book was so much better in every way though, I wished they would of kept it how it was instead of rewriting the whole thing. If you didn't read the book do so, it won't take long and I bet you the price of your next movie ticket that you'll agree with me. Anyway the special effects were good I don't regret seeing it; it could of been so much better though. I can't understand why they changed the script so much. It was literally written for them. If you have the answers please let me know. I hope that helps. Worth $2 at redbox not theater prices.
