Playing a tense and anxious characters comes so naturally form Ryan Reynolds. His performance was the perfect example of a thought-provoking and seemingly-clueless and innocent character in such a brutal and surreal situation. This was one of the films out there that proved you didn't need an explosive and grand production to create such a lowkey great thriller. The cinematography and production was the magnificent standout for me. To create such a tense setting was a complicated concept to formulate, and yet this film did just that. Added with an explosive twist at the end, this was on its way to becoming a classic.
