I liked it... It had that "Keyser Sose" factor - it's just so much fun to watch when a bunch of people who think they know what it means to be tough and ruthless because they've been so successful at beating up on the weak and helpless suddenly find out the rules have changed, and now they're prey.
And it might have been a bit over the top but I really liked Christopher Walken's "You can be an artist at anything" piece.
