Why PG-13 Shark Movies Need to Evolve: A Review of 'The Devil's Mouth' (2026)

The Shark Movie Saturation: Why 'The Devil’s Mouth' Feels Like a Missed Opportunity

Lately, it feels like the film industry has been drowning in shark movies. Personally, I think 2026 might go down as the year we hit peak shark fatigue. Every few weeks, another fin-filled thriller surfaces, and while I’m a sucker for a good aquatic horror, the formula is starting to feel as predictable as a shark’s appetite. Enter The Devil’s Mouth, a film that, on paper, seemed like it could break the mold. Spoiler alert: it didn’t.

The Cave Conundrum: When Setting Outshines Story

One thing that immediately stands out is the film’s setting—submerged caves in Thailand. From my perspective, this could have been a game-changer. Caves add a layer of claustrophobia that open water can’t match, and the production design here is genuinely impressive. The titular Devil’s Mouth, in particular, is a standout—a menacing, almost mythical entrance that promises danger. But here’s the kicker: the setting feels wasted. Instead of leaning into the unique tension of being trapped underground with a predator, the film falls back on tired tropes. What many people don’t realize is that the cave could have been a character in itself, amplifying the horror. Instead, it’s just a backdrop for the same old drama.

Characters You’d Feed to the Shark

Let’s talk about the characters, or as I like to call them, the shark’s buffet. Kathryn Newton is the lone bright spot, bringing her usual charm to a role that desperately needs it. But the rest? Yikes. Lana Condor’s Max is so unlikable that I found myself rooting for the shark to take her out first. And don’t even get me started on the generic teen leads who blend together like a school of fish. If you take a step back and think about it, the first act feels less like character development and more like a setup to make you hate these people. Which, I guess, is one way to build tension?

The PG-13 Problem: When Sharks Go Soft

Here’s where I get really opinionated: PG-13 shark movies are a crime against cinema. What makes this particularly fascinating is how the rating neuters the very thing that makes shark films thrilling—the kills. In The Devil’s Mouth, every attack is quick, bloodless, and forgettable. It’s like watching a nature documentary where the predator misses every time. What this really suggests is that studios are more interested in appealing to a broader audience than delivering a genuinely scary experience. And let’s be honest, if you’re making a shark movie, you’re already in niche territory. Why not go all in?

The Shark Itself: A Mix of Cool and Confusing

A detail that I find especially interesting is the choice of a bull shark as the antagonist. Bull sharks are known for their aggression and ability to thrive in freshwater, which could have added a unique twist. The film even nods to their hunting tactics, like ramming prey. But then it undermines itself with inconsistencies—like the shark swimming backward despite the film explicitly stating they can’t. It’s a small detail, but it’s emblematic of the larger issue: the film can’t decide if it wants to be realistic or just another popcorn flick.

The Bigger Picture: Why Shark Movies Need to Evolve

If you ask me, the problem isn’t just The Devil’s Mouth—it’s the genre as a whole. Shark movies have become formulaic to the point of parody. Trap a group of people in a dangerous situation, throw in a shark, and watch the chaos unfold. But what’s missing is innovation. Why not explore the psychological toll of being hunted? Or the environmental implications of human-shark conflicts? This raises a deeper question: are filmmakers content to churn out the same old stories, or are they afraid to take risks?

Final Thoughts: A Missed Bite

The Devil’s Mouth isn’t a terrible movie, but it’s far from memorable. It has moments of potential—the cave setting, Kathryn Newton’s performance, the bull shark’s unique traits—but they’re drowned out by lackluster characters, predictable plot beats, and a PG-13 rating that feels like a straitjacket. Personally, I think this film is a missed opportunity, a reminder that even the most intriguing premise can’t save a story that refuses to take risks.

If you’re craving a shark movie, The Devil’s Mouth might tide you over. But if you’re looking for something that pushes the genre forward? You’ll need to keep swimming.
