To a far greater degree than the vast bulk of movies, TV shows, especially genre ones, spawn pretty fanatical followers. And, as you suggest, rather than ragging on a series for wasting 2 hours of their life, they just stop watching.

Among the series you listed, I see several that, for me, were basically meh superhero shows I might have watched an episode of and then tuned out. There’s too much good TV for me to bother with stuff that I suspect I’ll be indifferent to in the 5 hours or so if TV I watch in a week.
