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.
This is one of the very few times I think “well, you’re entitled to your opinion, but you’re dead wrong”.
In my head the only Star Wars canon consists of IV,V,VI, the bare plot of the prequels, Clone Wars, Andor, and Rogue One. All else is tacky gold decoration.
