Prom Night III (1990) is a movie I recently watched on YouTube. The storyline follows Mary Lou's return to her haunted high school where she manipulates a young man to do her bidding. He thinks he's in love and as long as Mary Lou gets to start another killing spree she'll help him go right along thinking that. This movie is codirected by Ron Oliver (Big Fat Liar 2) and Peter Simpson (directorial debut) and stars Tim Conlon (Angels in the Outfield), Cynthia Preston (Carrie) and David Stratton (Things to Do in Denver). The storyline in this is pretty lazy and doesn't have much going for it. The acting is dreadful but there's a few lines here and there that will give you a good chuckle. The circumstances are crazy unrealistic but I did appreciate some of the sets and how they created the scenes despite an obvious limited budget. There was some creative elements. Overall this is a below average addition to the genre that isn't a complete waste of time. I'd score this a 3.5/10.
