13 Small Changes That Would Make Terrible Movies Awesome
4. There's No Dumb Twist Ending - Switchblade Romance
Alexandre Aja's 2003 horror film is a taut, exceptionally disturbing exercise in grisly suspense for the majority of its runtime...and then a grossly unnecessary plot twist shows up to ruin it all.
Marie (Cécile de France) and Alex (Maïwenn) spend most of the movie fleeing from a deranged killer, before it's revealed that the killer is actually Marie herself, and the serial killer only exists in her mind, a fictional construct that she's deluded herself into "saving" Alex from, being obsessively in love with her.
It's a pointless and eye-rollingly needless additional wrinkle in a movie that was doing so well without it. A much simpler, more straight-forward ending where the original demented killer is defeated would've been so much more satisfying and a lot less objectionable by any measure.
This was a near-classic horror film that was effectively ruined by its atrocious ending, which colours the entire rest of the movie and makes revisiting it a sour experience indeed. Change those final ten minutes and this is basically a masterpiece.
