47 Meters Down
Yes, I admit, the premise for 47 Meters Down is on the ridiculous side, but I'm telling you — it's good. Mandy Moore and Claire Holt star as two sisters who decide to go cage diving with great white sharks while vacationing in Mexico. Unfortunately the rusty chain holding up their cage snaps, sending them careening . . . wait for it . . . 47 meters down to the ocean floor. With oxygen running out and no way up to the surface except through a horde of hungry sharks, both physical and psychological horrors begin to overtake the two. It's extremely entertaining, and despite being a shark movie fanatic, the ending took me by complete surprise.
