12 Angry Men

This is incredible. At what it sets out to do, it's just perfect, and I don't think I can say that about another film. Of course the writing is incredible but even things like the camera work, which in a one room drama could have been incidental, does such an incredible job of conveying emotion. Then the tiny details, like the timing of the rain, and the introduction and goodbye at the end, it all comes together into the most captivating thing I've seen in a long time. The 'people sat in a room talking' is a genre I love so much and I don't think this can be beaten.
