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.
“there’s a good idea somewhere” So many shows don’t know how to come to grips with the main thesis, so the producers and writers just do what they know how to do; write soap operas.
