You know that by the time a franchise reaches the fourth sequel, usually the producers scrap the bottom of the barrel. In the case of Prom Night IV Deliver Us From Evil, this is exactly the case. This is a film that does not succeed in any shape or form whatsoever. The Prom Night series have only two good films in the series, the first two. But the third and fourth entry are absolute garbage. I found the film to be painful to watch in every respect and quite frankly almost a chore. I needed to watch this film so I could review the fourth entry and let people know how shitty it really is. This is the worst of the Prom Night films. The film lacks everything that has made the first two worth watching. This final entry in the Prom Night franchise is a drastic departure from it's predecessors. Like every film in this series, none of them have a specific killer, for example Friday The 13th has Jason, Halloween Michael Myers. This fourth film is a mess with a bad script, bad acting, and poor buildup. If you've seen the first three, then skip this film, it has nothing in common with the original film or its second film, plus the third film was a comedy horror film which was also poorly executed. The film suffers from cliches and predictability, and the element of surprise that makes a good horror film are absent. There could have been something watchable on screen, but unfortunately I consider this a missed opportunity and I view this film as one of the worst horror films ever made.
