Thrash Review: A Shark Film That Barely Bites

A random Facebook scroll on an ideal Sunday landed me on a trailer of a new Netflix movie, Thrash. A shark attack film set against a flooded town, with people trapped inside homes while predators move through the water- it looked like the kind of setup that could at least deliver some tension.

So, when the movie arrived on Netflix on April 10, 2026, I pressed play, expecting at least a basic thrill- a film that could keep me on edge for 90 minutes. Instead, within the first few scenes, it became evident that this is a shark film with no bite.

The film failed to build dread, did not create urgency, and never once made you feel that anyone was truly in danger. Worse, it lays out its entire trajectory so early that the rest of the film feels like a slow, predictable formality.

What made films like Jaws work was not just the shark, but the anticipation of it. The fear came from what you could not see, from how the film held back.

Thrash does the opposite. It shows too much, too soon, and still manages to create nothing out of it.

No Tension, No Payoff

The biggest issue is simple: the film is not thrilling.

There is no sense of build-up in how scenes are constructed. Moments that should gradually tighten the screws- rising water levels, confined spaces, the presence of a predator- are rushed through without any sense of rhythm.

The film mistakes movement for tension. Characters move, situations change, sharks appear, but none of it is staged in a way that makes you uneasy.

Even the attacks feel oddly weightless. There is no dread leading into them, no shock when they happen, and no lingering impact afterwards. The film does not understand pacing, and because of that, it never earns its set pieces.

The background score tries to compensate, but it comes across as generic and overused. Instead of enhancing tension, it signals it in the most obvious way possible, which only makes the lack of actual suspense more noticeable.

Predictability That Drains All Engagement

Thrash reveals its hand right at the onset, almost within the first few minutes.

You can map out the film within the first few acts- who will survive, who is marked for death, and roughly when those moments will come.

The narrative follows a rigid survival template and never deviates from it. There is no attempt to subvert expectations or even rearrange familiar beats in an interesting way.

What makes this worse is how transparently the film sets up its characters. Certain individuals are given just enough screen time and backstory to signal their fate.

Others are positioned as obvious survivors without facing any real threat. By the midpoint, you are not watching with curiosity, but with confirmation.

And when a film becomes that predictable, tension disappears completely.

Too Many Characters, Too Little Depth

The film splits its focus among multiple groups: stranded civilians, a pregnant woman trying to survive rising floodwaters, and a marine researcher meant to provide some scientific grounding. On paper, this could have created intersecting narratives with varied stakes.

In reality, it spreads the film too thin.

None of these characters is developed enough to feel real. Their motivations are surface-level, their decisions often feel convenient, and their interactions lack any emotional weight. The film gives you just enough information to identify them, but not enough to care about them.

The dialogue does not help. It is functional, often expositional, and occasionally unintentionally flat in moments that are meant to carry emotional weight.

Conversations feel written to move the plot forward rather than reflect how people would actually react in such situations.

As a result, when characters are put in danger, there is no investment. And without that, even the idea of survival loses meaning.

A Strong Concept, Undermined By Execution

A flooded town overrun by sharks is a solid concept. It is inherently visual and full of possibilities- tight indoor spaces, murky water, limited visibility, unpredictable attacks. There is scope here for inventive staging and sustained tension.

But the movie never fully explores this.

The film relies on repetition rather than escalation. Similar scenarios play out again and again with little variation.

Characters are trapped, sharks approach, someone reacts- repeat. There is no layering of danger, no increasing complexity in how situations unfold.

Even the use of space feels underdeveloped. The flooded environment should have been a character in its own right, constantly shifting and creating new threats. Instead, it feels like a static backdrop.

Technical Aspects That Stay Flat

From a technical standpoint, the film is consistently underwhelming.

The film’s cinematography lacks atmosphere. The framing is straightforward, often missing opportunities to use shadows, reflections, or obstructed views to create unease.

The film’s editing is one of the biggest issues. Scenes do not build; they simply progress. There is no sense of rhythm, no control over how information is revealed.

The visual effects are inconsistent. At times, the sharks look passable, but in many sequences, the interaction between actors and CGI feels disconnected. This weakens the impact of already undercooked scenes.

The sound design and background score don’t elevate the material. Instead of enhancing tension, they underline it in the most obvious way, which becomes repetitive.

There is no unifying visual or tonal identity. The film feels assembled rather than directed with a clear vision.

Missed Opportunities At Every Turn

What stands out most is how many opportunities the film lets slip.

There are moments where it almost hints at something more effective- a tighter sequence, a better use of space, a brief suggestion of tension- but it never follows through. Every potentially engaging idea is either rushed or underdeveloped.

Even the emotional stakes, which could have grounded the film, are treated superficially. Relationships are introduced but not explored. Conflicts are hinted at but not resolved in any meaningful way.

It is not just that the film does not work—it never really tries to go beyond the obvious.

At the end, all I would say is that Thrash is not just a weak shark film- it is a forgettable one.

Movies like Thrash should never be made, as they not only insult the genre but also the viewers who love movies based on shark attacks.

I would go with 1/5 stars for this insipid tale of a shark attack.
