I don’t mean stuff that was obviously bad on sight (to you) and so you didn’t bother with, or even necessarily content you just checked out of before the first episode was done. But a series that you ultimately felt wasted your time and abandoned due to its total lack of quality.
I love zombie media, and Walking Dead season 1 was really good, thrilling even. And then it changed to really thick drama with occasional zombie somewhere and I lost interest. Then my SO was watching it and they were… herding zombies?
