With decreasing air supplies and massive sharks lurking nearby, the siblings must find a way to escape their underwater prison. Every faint breath, calculated move, and each precious drop of blood carries immense significance.

The holiday-turned-nightmare thriller directed by Johannes Roberts faces the inevitable comparison to the iconic, Jaws. While some say it can't match the iconic classic, others praise the film as "innovative", and "surprising", especially its clever twist ending, reports .

Johannes Roberts' gripping movie took the summer season by storm, reaping $62.6 million worldwide, an outstanding return on a $5 million budget. Its triumph led to the commission of a sequel, 47 Meters Down: Uncaged.

An awestruck critic praised 47 Meters Down as "a tense and claustrophobic thriller that is far greater than the sum of its parts", adding: " A PG-13 rating CG shark horror that revolves around some annoying tourists? Rated only 50%~ on Rotten Tomatoes and mid 5's on IMDB? Sounds sh*t right? Never watched it until recently and I have to say, I was extremely pleasantly surprised. If you haven't seen it, I would recommend giving it a go. Honestly it's pretty nonstop white knuckle, butt clenching thrills. Would recommend."

Discussing the film's visual appeal, another Redditor remarked: "I personally really liked the movie from a cinematography standpoint," while elsewhere, one person believes the film "definitely deserves more credit than it seems to get."

Currently holding a 53 percent score on Rotten Tomatoes, there are viewers who believe it's quite apt: "I think the ratings reflect the quality of the movie pretty accurately. It's an interesting premise but mostly boring and contrived. The 'light a flare to illuminate a bunch of sharks about to eat you' bit was like the one cool visual moment, absurd as it was. Honestly, while the sequel was just as dumb, it was at least scary, with big blind sharks stalking teens through a tunnel system."

Conversely, another viewer concurred with the lacklustre ratings, saying: "What a goddamn nightmare of acting though. There's a reason for the 50%".

Some cinema-goers reckon the flick didn't quite hit the mark, with one commenting: "47 Meters Down has an intriguing premise, but its execution falls short in terms of direction. The tension wasn't sufficiently sharp to keep me on the edge of my seat, and while the cast is competent, their performances are somewhat underwhelming. The movie itself also suffers from a touch of corniness. Grading: C-".

Yet another viewer reckoned the criticism was overblown, remarking: "I am not sure why this movie has such poor reviews. I enjoy realistic horror/thrillers. Sure, I may not know much about scuba diving, but I feel that the movie did accurately portray the dangers of not doing research, going off with strangers, and hypoxia - which is one of the biggest concerns in diving. This movie really had me on edge. I think they did a great job and it's one of my favorites."
