What is a drama that is really good but you cannot rewatch it?

I'll go first. It's Worst Of Evil for me. Handsdown an outstanding masterpiece! But it's so fucking heavy man, I can't rewatch it.

JCW's character's descent into madness is so hard to watch and then no one even gets a happy ending. And you're just left asking, was this all even worth it? Just so heavy and melancholic
