An okay cult slasher

Don't think I've seen any of the original four Prom Night movies since they first came out, so I'm rewatching them over this Halloween. This one was actually a fan-edited 'Director's Cut'. It restores several deleted scenes and removes the subplot about an escaped sex-offender (which wasn't an original part of the story). Jamie Lee Curtis stars as Kim, a high-schooler whose 10 year old sister Robin died tragically years earlier. This year the school prom happens to fall on the sixth anniversary of Robin's death, and someone is hunting down students who were present when it happened. Pros: The performances are good, it's well shot, and it delivers the requisite '80s T&A. Cons: After the atmospheric opening with Robin's death it's an hour before anyone is killed, a couple of kills fall outside the killer's supposed motivation, and it's a bit light on the gore. It's also slow at times compared with later, better-known slashers. Interesting to revisit - but I'll probably give it another forty years before the next watch. 6.5/10.
