10 Endings That Make Movies Impossible To Rewatch

4. Marie Was The Killer (Somehow) - Haute Tension

Alexandre Aja’s French slasher flick Haute Tension (aka High Tension in the US and Switchblade Romance in the UK) has everything a horror fan could want - graphic gore and violence galore - but in a genre whose audience is forever trying to second guess who the crazed killer is, Aja resorted to a plot twist that didn’t make any sense at all.

College student Alex and her friend Marie are off to the former’s parent’s farmhouse for a couple of days of quiet study - a weekend retreat that goes horribly awry when a sadistic, homicidal maniac breaks in, kills Alex’s family and abducts her leaving Marie to come to the rescue. But, after much murder and bloodshed, it turns out that Marie - obsessed with Alex and suffering from some kind of split-personality disorder - is actually the killer.

It’s a common horror genre gimmick that when done well can be quite enjoyable but thinking back over the film - including scenes in which Marie and the ‘killer’ are in different places at the same time - the student-turned-serial killer twist was just plain illogical.
