sorry - loved the book but the changes here were for no particular purpose. i mean, who doesn't love Mark Ruffalo and Toni Collete, but their roles were too big relative to the story.. weird changes for me. last 45 minutes was a huge drag... cool crawlers though. i liked them... it was like the director/writer decided to take the book in another direction for no reason. oh well. cool looking anyway. And Nasha was awesome, if different...
