Mary Lou is brought back from the dead once more to wreak havoc at Hamilton High. Alex Grey is the poor sucker that has to do her bidding. The only movie in this series that I like is Prom Night 2. It's actually one of my favorite horror movies, and extremely underrated. Yes, the second movie was campy, but it was actually suspenseful as well. They throw the suspense out the window in favor of laughs. Not only is it terribly unfunny, but downright boring. I didn't care about anybody in this movie except for one person, and that was Sarah (Cynthia Preston) She felt like the only real person in this movie. Even Mary Lou bugged me in this movie. There is gore in this movie, but it's played for laughs. Most of the deaths are stupid. Tim Conlon makes for a bland lead. I wanted to slap him silly at times. Cynthia Preston is very solid as the love interest. She comes out of this crap looking like a champ. Courtney Taylor is nowhere near as seductive and sexy as Lisa Schrage was as Mary Lou. She tries hard, but just doesn't have the charisma or the script to work with. The ending is a real downer and p*** me off. This movie is marred by a lot of rampant stupidity. The second movie had the perfect balance of scares and humor. This movie focuses way too much on silly comedy. I'd skip it if I were you3.3/10

The third film in the "Prom Night" franchise continues to steer the series further away from its slasher origins and closer to the supernatural and, well, corny. Mary Lou, the undead bombshell from the previous film, returns to Hamilton High and takes a liking to Alex Gray, a football player who is bored with his current situation and craves a bit of spice in his life. When the two hook up, Alex gets more than he bargained for, although, strangely enough, doesn't seem all too shocked or surprised by a lover who is more than thirty years past her expiration date and who will do literally anything for him, which includes killing his teachers and classmates in only the most ridiculous ways possible."Prom Night III: The Last Kiss" is the sort of film that doesn't take itself too seriously, and upon viewing it, neither should you. There are no serious thrills to be found in this often cartoonish and over-the-top sequel, but there is plenty of fun to go around. From the silly death scenes, which are complimented by comically underwhelming reactions from star Tim Conlon, who appears to have little to no regard for the value of human life. Likewise Mary Lou, played this time around by where-is-she-now Cyndy Preston, gives Freddy Krueger a run for his money with the amount of cheesy one-liners that are thrown around and with the way she lashes out with those ridiculously long fingernails (side-bar: I'd hate to be Alex's back). There are also other little moments, such as the school-intercom gags and the Charlie Brown-ish phone call that Alex makes to his parents. These bits ensure that the film is hardly threatening in the slightest, and at best, is a light-hearted late-night romp that takes a certain sort of mood to appreciate. Put simply, it's a stupidly funny horror comedy that won't fail to entertain, even if it tends to induce a few facepalms. This film is best taken with a grain of salt.

This movie is not excellent but neither horrible: first of all is not even horror, it's more like comedy, you'll laugh your butt off. The ending is terrible, I didn't even understand it, I hated it! The deaths are very cheap and stupid... I don't even want to get started on Mary Lou, It's not even the same actress who played her on the second movie, Whenever she kills someones she leaves it up for Alex so he can bury them and he always says ''That's it Mary Lou, It's over'' but then little miss tramp resolves it with a kiss and moans which leads up to sex...Alex plays mister cheater and then comes to his girlfriend and cuddles up???It's edited in DVD, why???I have the double feature by Artisan on DVD, because I collect movies and anyone who collects them should have the prom night movies...I really give the movie 5 out of 10, but the ending....ZERO!!!

This wasn't the greatest sequels of the genere, but it has a lot of bright spots through the movie. This Mary Lou was a lot more sultry than the one in the second movie. Mary Lou was vile, but then again, she was a lot clever than usual. I liked the part where she seduced the pawn to her scheme. And I also liked the part when the football turned really deadly. And what do you have to say about that? SCORE!The only downside of the movie is there are a few well known stars in this movie, however, I enjoyed the plot, the storyline and the results of what went on throughout the movie. It could use a little more scare factor, and there's happen to be some comedy as well. It was fair, and slightly better than the second one in my opinion. Rating 2 out of 5 stars. 5 out of 10.
