Its hard for modern crime films to not borrow a bit from Heat. 'Cause, well, its really good. I don't know that there's been many contemporary crime flicks to compete with it since it came out.
Killing of a Chinese Bookie is terrific. I wasn't very familiar with Cassavetes but I knew his reputation as a kinda cinema verite talky proto-indie filmmaker. So, when it turned out to be a really cool (if weird) noir movie, I was pleasantly surprised. I heard that "Gloria" is another good Cassavetes crime flick, but that's just by reputation. Its about a tough moll who helps out a street kid while fighting the mob.
