This is a very well-made movie with no coherent storyline. The story has something to do with racial enmity, gangs, slavery, a young boy's grudge, political corruption and a few other things, along with a hackneyed love story and and a lot of wishy-washy character development.
However, this movie is worth watching for Daniel Day Lewis' performance alone. He steals this show, playing a hardened "gang" leader who considers himself a "native American" and gives no quarter to any person arriving on a ship from abroad. He is a classic thug with a lot of flare and also the only reason I watched the entire, drawn out 180 minutes of this mega-flop.
The movie is also quite funny at times. My favorite is probably a scene where an actor crudely playing Abraham Lincoln dangles from the scaffolds in the background as the thugs shoot and knife it out.
This is more of a modern art piece: it makes no sense whatever, but it's fun to look at.
