I'm somewhat this way, but more than somewhat when it comes to TV shows. I think something like 80% of my favorite shows were cancelled early. Firefly, Freaks & Geeks, Shadow & Bone, ...
Perhaps I should set up a Patreon where people can give me money to not watch things.
(Admittedly, this may be a mathematical artifact. Cancelled shows have less opportunity to decline in quality. At one point, The Dragon Prince was my all-time favorite show. I haven't even bothered to watch the last several seasons. It is even possible that the people cancelling the show are able to accurately predict that something is going to go downhill in the future, though I doubt it.)
For what it's worth, I watched the show while working/cleaning and the later seasons felt pretty decent. Its seventh and (I believe) final season is premiering in two days. I can definitely feel the influence of Aaron Ehasz, and although I've probably aged out of the target demographic, the ATLA-like worldbuilding/character writing is nostalgic. Not bad to have on in the background IMO if you ever get curious about what happens.
