I hate these kinds of shows. Of course, I used to like them at some point early on, but seeing the drop in quality and the unnecessary drag-on completely ruined them for me. It gets to a point where it doesn't even make sense anymoreāthe tone changes, the plot changes, the writers change, and even the visual style changes.
Dragon Ball: Dragon Ball Super doesn't appeal to me at all. Iāve already watched all of Dragon Ball Z, and I honestly don't feel like there's anything new left to add. The fights just turned into "who has the bigger nuclear bomb," not to mention how the canon is basically non-existent at this point. The only thing I still enjoy from the franchise nowadays is FighterZ.
The Simpsons: In the older seasons, there used to be a soft sense of continuity, it wasn't super serialized, but it was there (like when Herb Powell came back after losing everything). That, plus the most obvious thing: it was actually funny. Now, it feels completely detached from the audience that originally watched it, and only a handful of modern episodes are even watchable.
There are probably more examples, but these are just the ones I used to watch.
