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.
Gilmore girls, back when it was airing I had a reason to record the airings and check the quality and it was like if you designed a show specifically about nothing I can possibly care about.
