(I haven't read the book) The movie was confusing. If you feel this way it's not you. It felt like the plot was constantly changing. Once you think you've grasped the story line it changes. A lot of emphasis is put on the effects and action scenes not so much committed to moving the story forward. Characters disappear. Where did they go? 2.5 hours is a long time to not understand what's happening. I'm gonna catch the sequal just for closure. P.s. don't forget the closed captions. There's a lot of whispering.
