This has got to be one of the funniest movies I have ever seen. Altman's first major movie has such memorable and unique characters that were pulled off with such perfection (especially by Donald Sutherland and Elliott Gould) that by the end it's like losing close friends only two hours after meeting them. Altman's trademark style (of overlapping dialogue) captures the mood, even at the expense of jokes. This helps immensely with the replay value of both the comedy and the movie as a whole.There were some events that dragged on a bit, but they were few and far between. It definitely felt a little too episodic to be a movie; the style works better as a TV show. Thus the movie wasn't as cohesive and parts didn't flow as well as some of Altman's other movies. These are otherwise small qualms with an altogether engrossing and effective character-driven comedy.
