A lot of the comments have been about the film's relationship to the nature of violence, and it's true that it is a violent film. However, that's not the point of the movie. The film starts showing a young man sitting in the dark. He comes out into the light and walks slowly to where the action is taking place. He is dull, uninvolved, uninterested in what's going on. In the beginning, events happen to him. It is only after he is attacked by a hoodlum that he begins to take action himself. He volunteers for the mission to buy a gun and while on that expedition he is exposed to a wide variety of experiences that force him to become a more active personality. After his return he shows himself to be a take charge guy. The symbolism of the butterfly eggs is one of metamorphosis. The title "Boiling Point" has a meaning of change, the point at which water turns to steam. Finally, the last scene is of him in the same darkness as he was at the beginning, but this time when he emerges his movements are quick and jaunty. He is a different man.
