Harpoon is a deliriously mean-spirited treat (one not afraid to laugh at itself when appropriate). A film built around the premise of oceanic solitude and terrible secrets, it's also one which matches that premise, in character. To that, there is no one worth rooting for in Harpoon. No solid moral post to anchor against. Everyone in this film is painted as some shade of asshole; and I couldn't love it more for that.
Rivalries, dark secrets, and sexual tension emerge when three friends find themselves stranded on a yacht in the middle of the ocean under suspicious circumstances.
Director Rob Grant ('Alive', 'Fake Blood') does a fantastic job setting up the pins. The film opens with a foreshadowing sequence of violence between friends Jonah and Richard (Munro Chambers and Christopher Gray respectively); a scuffle over an alleged betrayal. It's insinuated that Jonah's slept with Richard's girlfriend Sasha (Emily Tyra), and so of course hell must be paid (appropriately enough, by Jonah's face).
A few knuckle sandwiches and a quart of blood later, Sash herself enters the fray, and attempts to snuff out the flames. From here, it's a boat trip and liquored stumble into perpetual treachory. A vile, cyclical ebb and flow born of the unraveling relationships so tenuously held together.
That's where Harpoon really shines. And depending on how dark your sensibility, likely where you'll derive most of the entertainment from.
The more each ridiculous secret is revealed, the further into abhorrence each of the three stranded sea mates grow, and the higher the probability for drastic retribution. What starts as simple bouts of fisticuffs, soon escalates into bloodshed. Violence is taken further and further, and by it's tipping point -- when things really begin to bubble and spill over, that's when Harpoon gleefully shifts its tone from dark comedy into shocking horror.
Fans of this particular brand of gruesome, of horror films that slowly -- but deliberately -- crank the dial on mean, while also allowing for reprieve in equally gruesome humor, are going to love being drifted away by Harpoon's narrative style. It comes highly recommended.
