Three people in one room, three different scores. That gap is the review.
There is a category of film that critics judge badly because they are judging the wrong thing. They watch it alone, in the afternoon, sober, taking notes, and then report that the plot does not hold up. It does not hold up. That was never the question.
The question is whether it holds a family on a sofa on a Saturday night. Thrash does, and the scores above show how differently it lands depending on who you are.
What it is
Netflix, released 10 April 2026, 86 minutes. Written and directed by Tommy Wirkola, the Norwegian behind Dead Snow and Violent Night. Phoebe Dynevor, Whitney Peak and Djimon Hounsou lead. Produced by Adam McKay.
A Category 5 hurricane hits the fictional coastal town of Annieville, South Carolina. The levees break, the streets flood, and the storm surge brings bull sharks into the neighbourhood. People trapped in submerged houses have to stay above the water. That is the entire premise and the film is honest about it from the first minute.
The thing nobody mentions
This film has been renamed twice. It was announced in 2024 as Beneath the Storm, became Shiver in 2025, and arrived as Thrash. Sony had planned a theatrical release and dropped it, and Netflix picked it up.
That history is worth knowing because it explains the film you are watching. This was built for a cinema, then rerouted to a living room. The scale is bigger than a streaming thriller usually attempts, and the polish is thinner than a cinema release usually allows. Both of those are visible on screen.
The honest problems
There is a lot of illogical material here. Decisions get made that no person would make, physics takes the evening off, and if you are the kind of viewer who asks how a shark got into a first floor corridor, you will be asking that question repeatedly.
The effects are uneven. Some shots are genuinely decent. Others look unreal enough to pull you out of the moment. In a cinema those shots would have been a problem. At home, on a sofa, with the lights off, they land as part of the fun rather than as a failure.
What it gets right for a movie night
Three things, and they matter more than the plot holes.
It is short. Eighty six minutes. Nobody checks the time, nobody falls asleep, and it finishes early enough that a school night survives it.
It needs no homework. No previous season, no cinematic universe, no character you were supposed to remember. Anyone walking into the room halfway through is caught up in about forty seconds.
It rewards the setup. This is a film built on sound and scale. Big screen, decent speakers, lights off, and it works considerably better than it has any right to. On a laptop with the lights on it would be forgettable.
Lights off, volume up, popcorn ready before you press play
This is not a film to half watch while scrolling. It is also not a film that demands your full attention for the plot, because there is not much plot to follow. What it wants is the room. Dark, loud, everyone on the sofa at the same time, snacks already made so nobody gets up. Set it up properly and a mediocre film becomes a good evening.
Why the daughter scored it highest
She gave it a nine. That is not a mistake and it is not teenage generosity.
A younger viewer is not carrying twenty years of shark films in their head. There is no Jaws comparison running in the background, no memory of Crawl doing the same thing better, no instinct to audit the physics. What is left is a fast, loud, genuinely tense survival film with a pregnant woman in floodwater and sharks in the hallway, and on those terms it delivers completely.
The adult scores of seven and seven and a half are the same film watched through more baggage. Nobody in the room was bored. That is the useful finding.
Decent movie night timepass, and it knows it
Good thrill, plenty of illogical material, effects that swing between decent and unreal. Not a film to think about afterwards. A genuinely solid pick if you have a large screen, good speakers and a family that wants ninety minutes of something loud. Turn the lights off and it earns its place.
Who should press play
Families with teenagers, which is where this scored highest. Anyone who enjoys a survival thriller and does not need it to be clever. Anyone who wants an evening that ends before eleven.
Skip it if plot holes genuinely ruin a film for you, if you are watching alone on a phone, or if you want something that stays with you the next morning. This one does not, and it is not trying to.
About this series
Home Movie Night is our running review format for things watched at home rather than in a cinema. Every film is scored by everyone in the room, because a film that a teenager loves and a parent tolerates is a different recommendation from one everybody agrees on. The scores go up as given, including when they disagree with each other.
What is playing at your place this weekend? Tell us in Delhi Foodiez, and tell us what you ate while watching, because that is half of a movie night anyway.
How we review. Watched at home on a personal Netflix subscription. No screener, no brand contact, no commercial arrangement. Photographs taken at home during the actual viewing.
