I gave up on endless anime after I binged 200 episodes of Naruto 20 years ago. I maintain that it's virtually impossible to sustain an interesting storyline over hundreds of chapters, and it either just becomes very silly or they end up basically recycling plot points.

Epicly long light novels are like that, too. Like in xianxia, they're weak and looked down upon, but, due to [secret hidden ultra advantage], they advance quickly until they can defeat the bullies. Which brings them to a new tier of power where they're weak and looked down upon, ...

Some series do a good job of expanding the scope of things so politics start playing a bigger role, and they interact with people multiple tiers above their power for more continuity/scope, and/or move to new worlds/environments with entirely new structures, etc.

Others just do the same thing over and over again. Most do both, lol.

I find I can't binge the same thing for more than a few weeks before I need a "palate cleanser" series before going back.
