Found footage? More like drowned footage, am I right?
*pause for laughter*
Seriously though, this is fucking garbage. The actual shark attack scenes are done well enough to show that a found-footage shark movie isn't a completely terrible idea, but this one quickly sinks under the weight of a colossally stupid storyline, three absolutely terrible characters who are a drag to spend time with even when you're just waiting for them to get eaten, cringeworthy dialogue and a couple of the shittest musical choices I've ever encountered in a film.
The traditional found footage problem of "why are you still filming?" is even more apparent than usual here - characters continue to use the camera while struggling to stay afloat in the ocean? Yeah, okay. Why don't you devote more screen time to a tedious love triangle and one character's heart condition, but have neither storyline go anywhere, ever? Oh, you did! Thanks, absolutely terrible movie!
