I do love a good shark movie. Most of the time, it comes down to the survival story: watching a single person or a group of characters try to escape a dire situation involving one of Earth’s most terrifying predators. But beyond the danger, these movies also make for a thrilling evening watch. So when Prime Video announced “The Devil’s Mouth,” its latest original movie, I was intrigued to see how this new shark thriller would stack up against the rest of the genre. Having now watched all 104 minutes of the survival flick, I’m left feeling more frustrated than entertained.Tom's Guide Verdict: 'The Devil's Mouth'Rating: 2.5/5 starsVerdict: “The Devil’s Mouth” offers some decent shark survival thrills, but predictable characters and frustrating decisions prevent it from reaching its full potential. Kathryn Newton is the standout, bringing much-needed emotional weight, while the film’s tense third act provides fun moments despite a lack of meaningful character development. Where to watch: "The Devil's Mouth" is streaming on Prime Video“The Devil’s Mouth” essentially feels like a claustrophobic version of “Jaws,” with a premise that’s almost an exact copy of “47 Meters Down: Uncaged.” It follows five college friends who embark on a guided swim through a remote cave system along Thailand’s coast. However, their exploration quickly turns into a nightmare when they realize there’s a deadly bull shark lurking in the darkness. Now they must work together to survive a predator that can strike at any moment.Prime Video likely has a new No. 1 movie on its hands, but “The Devil’s Mouth” suffers from one major problem that almost had me switching it off: its incredibly annoying characters. Not only did I want to scream at my TV, but I had absolutely no intention of rooting for these people, meaning there was no emotional investment whatsoever. So, before you dive into Prime Video’s new shark movie, here’s what I think.The scares are there, but patience is required
