"Prom Night IV: Deliver Us From Evil" is a serious (as in: no comedy touches) slasher that falls short in thrills & tension. Too bad, because it had a lot of potential. It's well-made, but severely dull in places. This time we have yet another stand-alone, unrelated sequel about a killer-priest (who is "evil beyond imagination") stalking & killing two couples in an isolated mansion. There are some supernatural undertones in the plot, but they are never explored. The budget on this production even seemed reasonably comfortable, as the cinematography isn't bad at all, often showing us some decent camera-movements on rails & even crane-shots. The acting is passable and the film opens really interesting. But then things fizzle quickly and the whole movie becomes uneventful. If they had simply amped up the body count & bloodshed, this sure could have turned into one of the unsung slasher gems from the early '90s. Now it just remains a curiosity for those interested in the "Prom Night" series. It's a strange franchise, to say the least, with this 4th installment presenting us yet again a different storyline. Interesting, but a failed effort altogether.
