I haven't watched much TV in years, but I did watch Dark Matter -- which despite the name wasn't very dark. Even with the situations, it was more light (campy sometimes) adventure with humor. That's what I needed, not serious stuff. That, and I've also always been a sci-fi fan too.

When I was really depressed about my life, I found sitcoms often upsetting. So I never got around to watching the Big Bang Theory until last year. I watched an episode a night until I saw all twelve years ending about two weeks after the series finale -- so good timing.
