Shark Horror "The Devil's Mouth" Storms Amazon Charts

August 5, 2026, 3:20 pm | Read time: 3 minutes

The charts of a streaming service like Amazon Prime Video are always a good indicator of what’s trending and particularly worth watching. If you have a subscription to the well-known streamer, you should check out “The Devil’s Mouth.” At least, the current popularity of the film suggests it’s worth a look.

“The Devil’s Mouth” Climbs Prime Video Charts

New figures from the portal Flixpatrol show that the bloody spectacle has made a particularly strong debut on Amazon Prime Video. Shortly after its release on July 29, “The Devil’s Mouth” shot to the top of the charts in several countries.

While on July 30 it was only in four markets, the number rapidly increased on July 31—just in time for the weekend. The film then reached number 1 in the rankings in 41 countries, including Germany. Since then, the results have declined.

As of August 5, it remains at the top in only 16 countries. However, it’s quite possible that the next weekend will bring another surge in viewership.

Cave Shark on the Hunt

“The Devil’s Mouth” is yet another shark horror film. Just in April, “Thrash” on Netflix caused a streaming frenzy. Now, the next fierce cartilaginous fish is on the prowl for humans.

As a farewell to their time together, five friends embark on a tour through the caves of “The Devil’s Mouth” in Thailand. But the trip turns into a nightmare when they encounter an unknown threat deep below the water’s surface. In the cramped darkness, panic and tension rise. As the group desperately searches for a way out, every decision determines their fate.

Low Instead of Highlight

But how good is “The Devil’s Mouth” really? While the high viewership numbers seem promising, appearances are deceiving—another similarity with “Thrash.” Whether you check Rotten Tomatoes or Metacritic for average critic ratings, the result is the same everywhere: “The Devil’s Mouth” is bad. Really bad.

While on Metacritic the average score of 46 almost passes as average, it’s a different story with the tomatoes. There, only 35 percent of professional reviews are positive.

Also very unusual: Fan ratings are usually more positive. But not here. Only an embarrassing 17 percent of users gave it a good rating. It looks even worse on Letterboxd: The film stands at a dismal 1.9 out of 5 stars. So if you don’t want to waste your time, you might want to look for another movie.
