I think the closest I’ve ever gotten to that was Rurouni Kenshin, at… let’s see… 95 episodes. That was many years ago.
A few years back, and I honestly have no idea why, I watched about 75 episodes of Fairy Tail (less than half of its run) before I burnt out on it.
There’s a few standard things I’ve watched that clock in at about 50 or 60 episodes - FMA and Brotherhood, DanMachi, SAO, Initial D and the like.
The vast majority of the things I watch seem to only last one season, or occasionally two.
I just wonder who they’re trying to convince here.
There have been piracy sites on the internet pretty much from day one.
And the biggest ones have gotten taken down pretty much from day two.
And new ones keep popping up.
