10 Great Horror Films Ruined By Terrible Endings

10. 47 Meters Down

A big dumb shark movie needs to be a big dumb shark movie, and there's not much more you can ask from it than that. 47 Meters Down embodies that faithfully, delivering a gripping, suspenseful tale of two sisters - Kate and Lisa - stuck at the bottom of the ocean in a dive cage as great white sharks circle ahead.

Not satisfied with sticking to one ending, 47 Meters Down doubles down on delivering two, becoming a confusing amalgamation of both happy and tragic tales that has to be unknotted by the time we're actually at the close of the film. First we see both sisters survive, only to cut and have Lisa stuck at the bottom of the ocean and her sister killed by a shark - the pair being rescued a result of nitrogen narcosis from huffing too much gas.

A bleak ending suits the films tone, but what was a sharp and snappy narrative becomes muddied by the bait and switch, numbing audiences to the reality of Lisa's situation with a messy finale to be picked out between all the dark shots of endless water.

If they were going to stick with the fake out, director Johannes Roberts should have gone with the original that saw Lisa die when the hallucination wore off. Might as well go whole hog here and avoid the cliches of the inexperienced diver surviving by virtue of her sacrificial mentor.
