47 Meters Down: Uncaged

Grant (John Corbett) has brought his family down to Mexico for his cave diving business. His daughter Mia (Sophie Nélisse) gets bullied at school. His step-daughter Sasha (Corinne Foxx) is not happy with her new family either. The students are set to leave on a glass-bottom boat tour. Sasha convinces Mia to join her friends for an outing of their own. Mia leads the girls in a dive of a submerged Mayan ruin. All goes to hell with they are confronted by a cave shark.

The underwater thriller has some appeal but also a lot of difficulties. Despite a big mask, it is often tough to differentiate between each character. It's not quite jumping the shark but it's in the ballpark. It's highly unlikely that sharks could grow to such sizes with only food found in the caves. It would be more reasonable to have an ocean going shark get accidentally trapped underground. The final ending is pre-determined by the movie setup. It ends exactly as I expected. The details are somewhat problematic. Instead of a flare, she needs to get a spear gun. The slow motion needs to be eliminated. There is no way that people are getting chomped and still walk away.
