(Hated Trope) Endings so awful they completely destroy the legacy of the media.

1. Two and a Half Men's final episode teased Charlie Sheen's character coming back and going to harm the other characters whilst also having insults to his character and Charlie Sheen himself. It's clear the director had a grudge and the ending where his character comes up to knock then get crushed by a piano before it cuts to the director before he says "winning" before getting crushed by another piano
2. This was an upbeat animated show about a magical teen princess. The writers desperately wanted a romantic endgame for her and her best friend, but the way they got there was essentially multiversal omnicide. To stop a villain, the main character unilaterally decides magic is the root of all evil and destroys it entirely. By doing this, she casually commits mass genocide against every purely magical being in the multiverse. It also triggers a massive apocalyptic event that violently crashes different dimensions together into a chaotic hellscape. But the show frames this horrific, mass-extinction catastrophe as a sweet, triumphant ending just because two teenagers get to hold hands in the rubble (Star Vs The Forces Of Evil)

Sherlock was never great, but ending is so offensively terrible that it makes me angry every time I remember it. The sister is literally the worst character I have ever seen in any media

Also, the fact that Sherlock and Mycroft just forgot they had a sister as one of the plot points is hilariously bad writing.

not Mycroft, just Sherlock. Still ridiculous

He has an idetic/photographic memory of everything but it only started at age 18. Everything else is forgotten.
