One of the last of the great early-mid 70s flicks. I watched this years ago and loved it, and recently I watched it again while attending a Hostage Negotiation course (the point was to demonstrate what not to do). A compelling character study, outstanding acting, and superb character development. Someone mentioned that the crowd is the most interesting character and that's true. They cover all moods that are conveyed in the film. SPOILERS. The "sex change" aspect nearly takes the film to the point of being ludicrious, but because it is based on an actual incident it would have been wrong to exclude it. Oh and the "I liked to be kissed" line is a classic.
