black water with sharks, and a couple more people. (spoilers)
essentially, some idiots get rightly eaten by a shark, in a near carbon copy of black water.
it's even the same plot device, boat....capsize...malevolent creature between them and safety, miles from anywhere. They get stuck into it by the 15 min mark, just like black water, a muted hint of character attachment and off we go, lets get these people eaten.
don't get me wrong, the first two acts are good. but the third act labors under excessive string section/shark swim-by build up. only to end with a blunt splutter/cop out, just like black water, weak finish.
there's some good stuff in there, but it made the characters look like idiots by having them do the exact cliched thing you knew they needed to do to ensure they'd swiftly become shark food.
