Blade Runner
As a kid the first time I saw this movie it all but blew me away. It struggles with complex ideas and scenarios. It does this the whole while you are lost in the depth of the characters, it was one of the all time great SciFi movies. The opening scene is amazing and one I can not get out of my head even all these years later. However there is one scene that I find amazing and delivered by the least likely of characters. I suggest if you haven't seen this movie that you do, in a way it puts things in a different perspective.
