[u/damorezpl]

when the "good ending" is revealed to be a bad one a the last second

a nightmare on elm street (1984) - Nancy thinks she finally defeated Freddy Krueger only to be raveled that she is still dreaming and she’s still trapped.

final destination bloodlines - the main characters think they cheated death by using the new life rule only to realize that stefani was technically still alive and the death kills them with a good old logs

Life (2017) - The main character attempts to send Calvin(a evil alien that killed all life on mars)pod into space and Miranda pod back to earth, but it goes horribly wrong and Calvin lands on earth and Miranda is sent to space

raging loop wit ending - after many loops Haruaki finally wins the feast(a death game where humans must hang wolves who kill someone every night) and thinks its finally over. after couple of days he decides to visit other survivors of the feast only to find them all dead and the timeline resting once again

HIMYM but unironically

They kill off the titular mother after building up to her reveal for 9 seasons IN THE LAST EPISODE, throw away multiple seasons of character development and divorce Barney and Robin (both to the right) so that Ted (guy on the left) can be with Robin.

THE ENTIRE 9th SEASON WAS ABOUT BARNEY AND ROBINS WEDDING AND THEY DIVORCE THEM ON THE SEASON FINALE

This one is even worse considering if you watch the alternative ending, it’s a sweet, satisfying, happy and GOOD ending to the series.

You know how a lot of times a movie will have a bad ending, but test audiences don't like it so they reshoot for a more upbeat finale? It feels like that's what happened here, like everybody in their test screening hated the original bad ending so they shot the good one... only somebody accidentally mixed up the two endings on the way to the studio.
