Bumping this because I just saw it. This movie had some special moments but it did fall short in many respects.
The acting, story concept and cinematography (what little I know about this) were great, but it was so bloody predictable. Also, I felt like I was watching Fight Club for hipsters.
Any of you saying you were completely mindfucked for hours and even days after viewing are seriously taking the piss. Yeah going crazy would suck, as if we didn't already know that. There weren't any crazy loose ends that really kept you thinking once the film was over either.
That being said, it was one of the better films of the last year and probably is in with a shout for best picture (I don't think it would be my pick though), I still need to see King's Speech and 127 Hours. The four other people I went with disliked the movie.
