TL;DR: Thrash is a messy yet enthusiastically entertaining Netflix shark thriller that blends Crawl’s hurricane survival with Jaws chaos, multiple storylines, and a shameless underwater birth scene. The tone wobbles between serious warning and silly B-movie fun, the CGI sharks are just good enough, and strong performances plus tense set pieces make it a worthwhile splash for creature-feature fans who enjoy ridiculous horror.
Thrash
Listen, fellow geeks, I sat down with a cold drink and zero expectations for Netflix’s latest creature-feature experiment, and somehow walked away both exhausted and grinning like I’d just survived a Jaws marathon during a category-five storm. Thrash, the new Tommy Wirkola-directed shark thriller that dropped on the streaming service this week, is not going to rewrite the rules of the genre like Crawl did back in 2019, but damn if it doesn’t throw everything—including the kitchen sink, three terrified kids, a very pregnant heroine, and a marine-biologist uncle—into the flooded streets of a South Carolina town and say “let’s see what sticks.”
From the opening frames where the hurricane slams into quiet suburban homes, turning perfectly normal living rooms into floating nightmares, I felt that familiar rush of “oh no, they’re really doing this.” Beds bobbing like possessed furniture from The Exorcist? Check. Flooded basements that look like they belong in a Resident Evil level? Absolutely. And then, because why not go full urban legend, a whole school of sharks decides to crash the party, cruising through what used to be Main Street like they own the place. If you’ve ever wondered what would happen if climate anxiety met pure exploitation cinema, Thrash is basically the answer written in blood and seawater.
I’ll be honest with you, my inner horror nerd lit up the moment I saw the premise. I’ve been a sucker for these “nature strikes back during a natural disaster” flicks ever since I was a kid hiding behind the couch during Shark Week marathons. There’s something deliciously ridiculous and yet strangely cathartic about watching ordinary people battle both Mother Nature and her toothy children at the same time. Tommy Wirkola, the guy who gave us the gloriously gory Dead Snow zombie-Nazi mash-up and the bonkers animated Spermageddon, clearly loves leaning into that chaos. He doesn’t just pick one survival story; he grabs a handful and smashes them together like a kid playing with action figures in the bathtub.
At the center of the storm we have Lisa, played with grounded panic by Phoebe Dynevor, a very pregnant woman who realizes far too late that leaving town might have been a smarter move. Her story alone could have carried a lean, mean thriller, but Wirkola isn’t interested in playing it safe. Instead, he weaves in Dakota, Whitney Peak’s agoraphobic young woman still grieving her mother and trying to ride out the flood from the supposed safety of her childhood home. Then there’s Dale, Djimon Hounsou bringing that quiet intensity we’ve loved since Gladiator and The Island, stepping in as the marine researcher uncle who’s basically the only adult who knows what the hell is going on with these sharks. And because one group of survivors apparently wasn’t enough, we also follow three foster siblings whose neglectful guardians treated the hurricane warning like it was optional reading.
This multi-threaded approach is where Thrash both gains energy and loses some of that laser-focused tension that made Crawl such a masterclass in B-movie suspense. Alexandre Aja’s alligator flick kept us locked in with one heroine, one location, and one escalating nightmare. Thrash spreads the love—and the chum—across several characters and storylines, cutting between them in a way that keeps the 79-minute runtime (yes, the actual movie is that brisk before credits padding) feeling like a frantic sprint rather than a slow-building dread machine. Sometimes that works beautifully; other times it feels like the film is hedging its bets, afraid to commit fully to any single point of view.
One sequence that absolutely lives rent-free in my head now involves those three foster kids having to dive into their blood-filled basement to grab essential gear while dodging sharks circling like they’re in the world’s worst game of Marco Polo. The practical tension in that scene—the way the camera stays low and frantic, the sound design turning every splash into a potential death sentence—reminds me why I fell in love with creature features in the first place. It’s pure, stupid, exhilarating fun, the kind of set piece that makes you lean forward on the couch and whisper “don’t you dare” at the screen even though you know exactly what’s coming.
And then there’s the childbirth sequence. Yeah, we’re going there. In what has to be one of the most gloriously shameless moments in recent mainstream horror, Lisa goes into labor right in the middle of shark-infested floodwaters. I actually laughed out loud—not because it was funny in a mocking way, but because the sheer audacity of it hit me like a perfectly timed jump scare. This is the kind of exploitation energy that mainstream studios usually sand off, yet Wirkola and company lean all the way in. It’s uncomfortable, ridiculous, and weirdly respectful of the genre’s pulp roots. You have to admire a movie that looks at the concept of “woman gives birth during a disaster” and says “what if we added sharks and made it even worse?”
Visually, Thrash punches above its Netflix weight. Originally developed with theatrical ambitions, the storm and flood effects hold up surprisingly well, especially at night when the practical water work and smart lighting sell the claustrophobia. The sharks themselves? They’re CGI, and they look it—especially in some of the brighter daytime shots where they glide through streets like slightly off-putting video game assets. But honestly, after sitting through the laughably bad shark effects in something like Under Paris, these guys are practically Academy Award contenders. They move with enough menace to get the job done, and when they’re half-hidden in murky floodwater or slamming into submerged cars, the illusion mostly holds.
The tone, though—that’s where Thrash gets a little drunk on its own ambition. One minute it wants to be a sobering look at climate consequences (hello, producer Adam McKay energy), the next it’s flirting with doomy satire, then suddenly it’s assembling a ridiculous montage of improvised weapons like it’s gearing up for a Evil Dead-style finale. I kept waiting for the movie to pick a lane, but it never quite does. Instead it tries to be everything at once: tense survival thriller, environmental cautionary tale, self-aware B-movie, and straight-up exploitation flick. The result is messy, but in the way your favorite over-the-top rollercoaster is messy—thrilling even when it threatens to fly off the rails.
Djimon Hounsou brings the most gravitas to the proceedings, his quiet determination cutting through some of the more cartoonish moments like a lighthouse in the storm. Whitney Peak does solid work making Dakota’s agoraphobia feel real amid the chaos, and Phoebe Dynevor sells the physical and emotional toll of late-term pregnancy during an apocalypse with believable desperation. The three kids are surprisingly effective too; they never feel like annoying plot devices, which is a minor miracle in this kind of movie.
If I have one real complaint beyond the scattered focus, it’s that Thrash never quite reaches the full horrific potential of its premise. The idea of climate change literally bringing apex predators into your living room is terrifying on paper. Rising sea levels, extreme weather, and nature’s revenge all rolled into one slimy package. Yet the film mostly uses those bigger ideas as window dressing rather than diving deep into the existential dread. It’s more interested in the immediate “how do we not get eaten” stakes, which is fine for a breezy 86-minute popcorn flick, but leaves you wishing someone had dared to go darker.
Still, when Thrash commits to the straightforward thrills, it delivers exactly what I came for. The intersections between the different survivor groups feel organic rather than forced, and the way side characters get turned into literal chum provides that classic creature-feature body count without ever feeling mean-spirited. There’s a late-movie weapon-assembly montage that had me cackling like I was watching Army of Darkness again, and the final stinger is abrupt enough to make you do a double-take before hitting the “are you still watching?” prompt.
In the end, Thrash is the kind of movie that knows exactly what it is: a love letter to the shark thriller subgenre dressed up in modern disaster-movie clothes. It’s not trying to be the next Jaws—that ship sailed decades ago—but it is trying to be the next fun, dumb, adrenaline-pumping ride you throw on when you want to forget the real world for an hour and a half. And on that level, it absolutely gets the job done.
Would I watch it again during the next big storm warning? Probably. Would I recommend it to my fellow creature-feature addicts who still quote Crawl’s crawlspace scenes? Without hesitation. It’s not perfect, it’s not revolutionary, but it’s enthusiastic, occasionally inspired, and unapologetically committed to putting people in the absolute worst situations imaginable and watching them fight their way out with whatever’s floating nearby.
