Anyone who’s deathly allergic to “bad”-on-purpose, winking-at-the-camera horror novelties like Zombeavers, Sharknado, or Hobo with a Shotgun should beware this review, because I’m about to be a lot kinder to the genre than it likely deserves.
Aquaslash is a retro novelty slasher about a killer waterpark slide that’s rigged with giant blades to chop idiot teens into pieces. The film is built entirely around setting up & executing that singular gore gag, so it has to save all of its bloodbath payoffs for the final 20 minutes. It’s cheap, it’s mean, it’s silly and, at only 70min in length, it barely registers as an actual movie. I still found myself ultimately having a great time with it despite my better judgement, though, which mostly came down to the film’s one saving grace: its central waterslide kill gimmick. The movie may be embarrassingly thin, absurdly insincere, and entirely reliant on one idea, but that idea is so impressively stupid and well-executed that it’s somehow worth the effort it takes to get there.
The setup to this film feels like any other post-Asylum exercise in ironic camp horror, but the follow-through is refreshingly sleazy in that context. Recent graduates from the fictional Valley Hills High School celebrate with a wild party weekend at the (equally goofily named) Wet Valley Water Park. This celebration is explained to be a tradition dating back to the 1980s, which allows the film to play around with Totally 80s™ nostalgia clichés in its 50-minute lead up to the waterslide gore promised in the title. That sounds like a mood-ruiner in the abstract, and it sometimes is when it comes to forced nostalgia signifiers like an abysmally shitty rock cover of Cory Hart’s “Sunglasses at Night.” However, it at least fully embraces the inherent sleaze of 80s slasher in a way that feels shockingly out of place in this kind of winking-at-the-camera novelty.
This is maybe the most enthusiastically committed illustration of Straight Guy™ sexuality I’ve seen since the hair metal music video was king. Young women’s bikini-clad breasts are used as bouncing eye-distractors, cocaine-sniffing surfaces, and splash zones for blacklight neon splooge – anything (within reason) they can get away with doing to titties to fill time before it can pull the trigger on the last-minute gore. That indulgence would be offensive if it weren’t so cornily outdated in a way that felt genuinely retro. As is, it’s overtly sexist the way an old stack of Playboys can be: quaintly so.
Bikini Babes & inane teenage drama are plentiful here; the gore is something you have to work for. The killer waterslide gag itself is truly incredible, though, and I believe the movie is short & harmless enough to get away with the delay. More importantly, it genuinely commits to the grotesque sleaze of the era it’s nostalgic for, as opposed to the Asylum style of retro novelty filmmaking that would rather pave over those unpleasantries with referential jokes & Z-list celebrity stunt casting. The sex is actually vulgar; the practical-effects violence is grotesque. All in all, this might be the best possible version of this kind of “bad”-on-purpose novelty that gives away its one original idea in its trailer & poster. My only major complaint, really, is that it should have been titled Slaughterpark.
