Gangs of New York (2002)

I finally watched Lars von Trier's Dogville last week and I loved it, so I figured it was about time to watch another of those movies I've been putting off for years because of its length, Martin Scorsese's Gangs of New York. 

It is set in 1863 when gangs ran the streets of New York and the government couldn't or wouldn't gain control of the city, and it mainly focuses on Amsterdam Vallon (Leonardo DiCaprio), a young man whose father (Liam Neeson) was killed sixteen years before by Bill "the Butcher" Cutting (Daniel Day-Lewis), the leader of the most powerful gang in New York, and is now seeking revenge.
