Query: Defines black humor

This is a witty, morbidly funny movie. It's weak in spots, andthe occult "magician" comments in Michael Caine's voice-over narration is perhaps a little misplaced. But it is an original movie, and entertaining, and as Michael Caine said when making it, "The thing is, this guy is murdering people, BUT YOU ARE ON HIS SIDE." After seeing this movie, you might find yourself looking at conniving rats in your life and thinking back to this movie! Even though Michael Caine plays an Englishman, it takes place in New York, and is a VERY American piece, in that it shows the absolute subtext of all American life is that you MUST be a success. I've seen this movie a number of times. The humor is twisted. But good...
