Worst movie ending ever?

Certainly not the worst ever, but it's one I always remember: Unfriended (2014 film). It's an OK horror movie but I actually thought that the ending was pretty clever and I liked the ending quite a bit...until they ruined it in literally the last 5 seconds for a pointless jump scare. It's so frustrating that if they had literally just ended the film 5 seconds sooner that it would have made the film better.

I always thought that movie was decent. Completely illogical but an entertaining experiment.
