As a scuba diver who has been fortunate enough to spend many hours with sharks (including in caverns), I can still give this movie 4 stars. Of course it's silly, but hey, we all knew we were going to watch a bunch of screaming teenage girls. Of course some of their decisions (including Dad's) were painfully stupid, but again hey, it's a horror movie! And as that, it's really well done and a lot of fun. If they had made all the right decisions the movie would be 20 minutes long and nobody would have been hurt. What's the point of that?? :-)

So, I do not know where to start with this movie.
1 - It is set in the most California, Mexico you can ever get.... I am not even sure there is a Mexican person in the entire movie. 2 - I don't think the actresses know how to swim. 3 - I am not sure the director knows how water works. 4 - No one seems to know how sharks work.
Put all three of those issues together and it really spoils what could be a good claustrophobic survival movie. Basic plot, four mildly attractive teenagers skip a shark viewing boat trip with classmates to go hang out at a sink hole where two of the girls (who are sisters) dad was setting up equipment for cave exploration. The girls decide to dive the cave and after a cave in blocks their way out they have to flounder and flail and hyperventilate their way out of their before they run out of air.... meanwhile they are being chased by a plot seeking shark that both senses sound/vibration and ignores it when the plot demands it. There is a scene where the girls are supposed to be swimming thru a strong ocean current but the director ramped that scene up to 1000% and you swear they were trying to swim thru a F5 tornado.... it's laughably dumb.

Saying it's strictly for teenagers is unfair to teenagers. Most of the teens I know are smarter than that. Huge blind sharks in a cave where there's nothing for them to eat? First they're out of air then they go back to find another exit? The water is sucking them down to where, exactly? Somewhere in there I just gave up on it. Stupid plot sloppy writing. Oh and how come nobody had any swim fins? Maybe they weren't in the movie budget

Pros: Good tension combination using confined spaces, risk of drowning, plus the immediate threat of sharks. The acting was acceptable. The actual shark models used looked great. Decent use of camera panning and perspective changes to augment the escalating moods throughout the film. Cons: Unfortunately, nearly every moment of suspense was far too predictable that it detracted from the horror of each situation. The audio and music crescendos intended to boost suspense and divert expectation, ended up giving each death away, as it's done in the same way as nearly every modern horror film. Situations like: "Hmm, I haven't heard any music for a few seconds during this monologue. It's as if character X is about to be killed in 3...2...1...aaaand yep, there they go..."
**Minor Spoiler** Other than clarifying the protagonist's geeky personality at the beginning of the film, the purpose of the bully seemed rather irrelevant to the movie, especially with the last scene she is in. Overall, the protagonist being a geek really didn't add anything to the film as well.

This movie is so bad, and so predictable, it surprised me (and I wasn't expecting much anyway). Most of the characters are very unlikable, and the relationships aren't supported by any reality, either in life or in death. Also, much of the underwater work was complete CGI-fakery.
All that being said, I was thinking of rating this movie 2 stars instead of 1... but then I watched the ending. It actually gets worse there (complete departure from laws of physics, time/space, etc.).
I was hoping for something closer to Sharknado, but got a cheesy knock-off of Jaws.

This is the kind of movie, like those jokes that are so stupid that cause laugh, but not because are that funny. This is so ridiculous that I don't even know where to start. The storyline is as absurd as a lion evolving to live inside an Egyptian pyramid and having a healthy diet of "fresh" human meat from Pharaoh's mummies and occasional tourists. It's a good movie if you are drinking and are the only guy with a few females watching. But for people who love cinematography this movie might be offensive. I truly don't see any diver or professional related giving any praise to this movie. At the end you can watch this movie and saying how much you enjoy it and why, but saying it is a good movie, only tells how much you lack in general culture.

Wow. Not only was this just a screaming girl movie that was chock full of previously used scenes and themes, the end was so absolutely completely absurd that it made me angry at myself for watching it. Badly written. Badly directed. Bad acting.
1.0 out of 5 starsTerrible Film, Don't Waste Your Money!

The first film, 47 Metres Down, was a far better film than this dire effort. I was a very experienced scuba diver and I've long since given up commenting much on the wildly unrealistic scuba diving in films but your air gauge never presents the contents of your tank in percentages and the time their already very low air lasts is of course ridiculous. The film was presumably for young teenage boys who might enjoy the screaming American brats more than anyone else would, the sharks were hopelessly poor. In fact, I can't think of anything I enjoyed about this film.
