10 Great Horror Movies That Fall Apart At The End

10. The Shallows

In The Shallows, med student, Nancy, is surfing in Mexico when a Great White takes a big chomp out of her leg. Knowing it's only a matter of time before succumbing to her injuries, Nancy desperately attempts to return to shore.

It's a bare-bones premise, but the creative and heart-pounding sequences are sure to keep viewers enraptured. While evading the toothy beast, Nancy seeks shelter on a whale carcass, creates rudimentary stitches for her wounds, and befriends a bird called Steven Seagull. (How has nobody made that joke before?) And since Nancy wanted to swim in this spot to honour her recently deceased mother, it makes her dilemma much more heartfelt.

Even though the fiendish fishy acts realistically at first, it turns into a cartoon character during the concluding act. At one point, it leaps into the air while letting out a defiant roar, despite the fact sharks don't have lungs. When it charges towards Nancy while on fire (yes, really), it's impossible to take it seriously.

Although the finale is meant to be epic, the poor CGI gives off major Sharknado vibes.
