Prom Night III: The Last Kiss is an interesting blend of comedy (very broad Student Bodies style splatstick) and horror, slasher and supernatural, and tongue-in-cheek and clever. It is mostly a lot of fun to watch and Taylor delivers some great zingers as Mary Lou. At 97 minutes, the film is a bit on the long side. At least ten minutes could have been cut from the final act within losing anything storywise. That said, it is consistently funny and quite often very entertaining. The production values are solid throughout and the script is helped out immensely by a game cast that appears to be having just as much fun as we are.
Please note, if you choose to watch this film (and it is indeed recommended), the DVD version released in a double feature DVD along with Prom Night IV: Deliver Us from Evil is a cut TV broadcast version. Most of the gore, swearing, and nudity is all but removed. However in the VHS version it is uncut, with all gore, profanity and nude scenes left intact.
