Television

At first, I was very, very cynical about Seven of Nine on Voyager. A tall, stacked blonde in a skin-tight bodysuit? Really? I thought it was just insulting pandering.

I was so annoyed that I would have given up on the show if not for the writers. She was a unique character with tremendous potential, and they took advantage of it. She had the acting ability to pull it off, too. She wasn’t simply there to coast by on her looks, and her character ending up adding value to the storyline. I’m glad I gave her a chance.

My first experience with this was as a kid, with the Fairly Odd Parents. Their baby (Poof) was just not fun. I felt betrayed and confused that a show I liked could go from my favorite thing to just plain bad lol

I know there have been others, but all my brain can think of is shows that I stopped watching because they got rid of a character. Fear the Walking Dead was alright, the plot wasn’t great but I really loved Nick’s character. Then they ruined it, because of course they did

Scrappy Doo.

I have had the reverse. I watched supergirl pretty much because it had the martian manhunter.

The Office. I stopped watching after Michael left and have only just started going back to finish it. It's kinda weird/cool still having "new" Office episodes, even if they aren't the best ones.

It was two characters, Greg and Tamara in Once Upon a Time. The show is campy, but it's still really entertaining. When those two showed up it went from campy, to very stupid. Idk how you can make a couple of characters in a fairy tale story seem completely unbelievable, when you're able to pull off the whole fairy tale to begin with, but that's what happened. I shut several episodes off as soon as those two popped up on screen. S3 Spoilers below:

I was super glad when they were finally killed.
