I saw this yesterday and really enjoyed it. Has Christopher Nolan ever made a bad movie? Well his record remains intact in my book.Awesome mind-bending visuals (Matrix, anyone?), interesting storyline, and decent acting. Ellen Page looked a little young for her character, but she pulled it off with her acting chops. I'm still not sure how to interpret the ending yet, so I'll probably need to watch it again.
