Just out of curiosity, have you liked any of the Coen brother's comedic films? O Brother Where Art Thou? Raising Arizona? They're all very quirky and filled with oddball characters. You either like them or you don't. There's no in between. Most people like to go through life thinking they're The Dude, when in fact, they're really Big Lebowski.
They've made other movies that are nothing like their comedies, though. Some really great crime films. Blood Simple, Miller's Crossing, and No Country for Old Men.
