Overall, a rather bad movie with a few redeeming qualities. Vampires in Las Vegas run amok and are hunted by a variety of police officers, who eventually defeat the vampires with the help of a sexy nun. Naturally. There are a number of flaws in the movies: day turns to night and night to day in the middle of scenes; characters' appearances change between cut away scenes, only two vampires combusted when exposed to daylight while many others walked around during the day without problems. The number of gaffes in the film provide the viewer ample opportunity to play "find the error." The main premise of the movie seems adequate (hunting down a 300 year old vampire who has returned to seek a new wife), but there are too many sub-plots floating around that provide tenuous links to the main premise.
Three characters stand out for their contributions to this film. Eric Etenari does an excellent job as the main vampire's henchman, a smooth talking, lady's man who provides the boss with his victims. Comic relief is provided by two legendary stars of the 1970s, Fred Williamson (who also directed the movie) and Richard Roundtree (best known for his role as Shaft). In some sense, Vegas Vampires seemed to be an effort, though largely deficient, to remember the days of the blaxploitation films in which Roundtree and Williamson starred in the 1970s.
