I've been working my way through Black Mirror after hearing so much about it, and it's a great show. Normally I'm not one to let what I watch on TV affect me, so through the first 2 seasons of episodes I was having fun watching the dystopian future stuff. Then I watched White Christmas, and after that I had to turn the TV off. That episode just got more mentally terrifying as it went along and the ending was such a gut punch
So ya, the writers are creative geniuses but now I have to take a break
