Re: What tv shows did you stop watching?
I can think about Fringe, which I watched about 6-8 episodes from the 1st season, didn't like and quit.
Recently: Scream, The Shadow Hunters and Santa Clarita Diet, watched only 1 episode via Netflix of all those series and quit.
I'm still somehow watching TWD and FTWD, I'm always thinking about quitting, because its pretty much the same predictable crap. I'm only watching for entertainment purposes, not giving much attention.
PS If you make a similar thread asking "TV series you always thought about watching, but never tried" I'd say Penny Dreadful, for some reason I never watched an episode, but always think about starting.
