Most underrated movie

[scottish]

What do you think is the most underrated movie and why?

[MKR&*42]

Exam (http://www.imdb.com/title/tt1258197/)

It's a pretty clever film tbh, but never hear people really talk about it much.

Oh or any of the cube films (2 had god awful acting but the general premise of the films was awesome).
