Gangs of New York

This is like watching the wild west, except they are in New York. The drama and intensity in this movie is so strong that its hard to believe that this is based on real things that happened. Also hard to imagine that New York was so rural. The characters are so rich, you are immediately drawn into the story. Especially compelling is the undertone of how people have used differences as reasons to fight, and founds ways to build alliances.
