[WARNING: the rating and review I give have the possibility to be subjective due to my preference for the genres, scenes or casts]

To be honest, I'm a little bit confused of this movie. I never good at math, so this movie really drained my brain (^_^;) It's entertained me, at least I know the existence of that theorem. The suspense theme is also entertained me (always), but I don’t know if I want to watch this movie again or not. The only thing that I like is the twisted plot in the end, but that doesn't enough to cover my confusion.
