20 TERRIBLE Horror Movies With INSANE Endings

2016's The Boy is an aggressively unremarkable film for the most part, one in which a nanny, Greta (Lauren Cohan), is employed to care for Brahms - a doll which an elderly couple uses as a stand-in for their late son.

For most of the movie we're led to believe that the doll is possessed by the soul of the late child, and honestly, it all feels pretty ho-hum and played out.

But then comes the bombshell of a rug-pull at the end, that Brahms actually isn't dead at all, nor is the doll actually possessed. 

Instead, the real, adult Brahms (James Russell) has been living in the walls of his family's mansion the entire time and wears a doll's mask over his face because... reasons. 

This leads to a climax in which Greta appears to kill Brahms, but of course, things are left just open enough for a sequel - a sequel which, bafflingly, returned to the whole possessed doll gimmick and more-or-less forgot about adult, flesh-and-blood Brahms.
