This is a very sordid film. I usually don't go for that sort of thing, but there are a lot of other good things about this movie that made me add this to my collection.
There is very good cinematography and camera-work in here, made even better by the special edition DVD transfer. I liked the old film-noir type atmosphere in the story, which is an interesting one overall.
There are no really good-guy characters in this film. Mickey Rourke plays the star of the movie: private eye "Harry Angel." He's somewhat of a low-life but so is everyone else. Lisa Bonet looks spectacular and has a steamy sex scene in here. Robert De Niro gets big billing but he doesn't have that many lines in this film.
The ending of this movie has a very unique twist to it, but it's certainly not a satisfying ending. It is one I should go back over after the next viewing and check for credibility. That's all I can say without using spoilers.
Overall, a sleazy but very intriguing story, with great atmosphere, that I enjoy watching every five years or so. Some would call this movie a modern-day "film noir."
