"Prom Night II: Hello Mary Lou" is one of my absolute favorite guilty pleasure slashers of the 80s, and my nostalgic love for that film undoubtedly contributed to me being a lot more tolerant and forgiving towards part III. "The Last Kiss" is a much worse film, but still vastly enjoyable and recommended to fans of late 80s/early 90s slashers.
"Hello Mary Lou" was a genuine slasher with a couple of comical touches. "The Last Kiss" is an out-and-out comedy with a handful of noteworthy slasher moments. Mary Lou resurrects again in the dungeons of Hamilton High, although this time in the luscious body of Courtney Taylor. Taylor is a prettier actress than Lisa Schrage - in my humble opinion, at least - but the latter had a lot more evil-witch charisma. Mary Lou takes control over the average-on-all-levels student Alex Grey, and her influence promptly turns him into a grade-A student and the best quarterback in the football team. Whoever questions Alex sudden progress, teacher or student, dies in horrible freak-accidents.
The kills in "Prom Night III" are gory, juicy, and sardonic, but not the least bit shocking. There's a teacher who gets impaled by ice cream cones (!) and a mixer shoved through the head, someone receives a battery acid shower ("Oh, she wasn't a person. She was a guidance counselor"), and there's a nice showcasing of a deadly touchdown. There's also straightforward slapstick, like when the principal cuts off his own finger during the festive opening of the gym, or through the announcements via the hallway intercoms ("Today's chess tournament is cancelled. All participants are requested to go to the library and play with themselves").
It's all good and cheesy fun for an hour or so, but after that "Prom Night III" quickly becomes dull and repetitive. The actual prom should be the high point of the film, but instead it feels like the longest and most redundant twenty minutes of the film, with Mary Lou dragging Alex into hell of some sort, and it looks a lot like the Hamilton High Prom of 1957.
PS: tip for all bachelors out there - find yourself a partner who starts baking cooking whenever she's upset or angry!
