Question

Exactly one year ago today, I saw a film that completely changed the way I saw films. The film in question? Steve McQueen's Shame. It very much opened my eyes to other films that were just as raw and unflinching. (For some strange reason though, I haven't seen it since that day.)

Anyway, my question to you, dear readers, is this: is there that one film you contribute to the way you watch movies?
