10 More Awesome Plot Twists That Totally Saved Terrible Movies

10. Brahms Is Living In The Walls Of The House - The Boy

2016 horror film The Boy centers around a woman, Greta (Lauren Cohan), who is hired by a wealthy elderly couple to be the nanny for Brahms, a porcelain doll that serves as a surrogate for their son of the same name who perished in a house fire 20 years earlier.

Though audiences naturally went in expecting an entertainingly trashy killer doll movie in the vein of Child's Play, The Boy is actually a frustratingly tepid effort where the doll only appears to move around off-screen.

But the end of the movie delivers a terrifically subversive plot twist that flips the entire scenario on its head, by revealing that Brahms is actually very much alive, having survived the fire and now living in the walls of his family's lush mansion. He has been sneaking around and moving the doll, giving the impression that it's possessed.

While the majority of the film was a disappointingly dull affair, this bonkers, expectation-defying twist brought it surging back to life for a finale in which Greta has to fend off the real, adult Brahms.

A less-thrilling twist came at the start of the sequel, though, which bafflingly retconned this ending and reverted to the idea of the porcelain doll being possessed, while the flesh-and-blood Brahms was nowhere to be seen.
