There's something to be said about how it's hard to really get attached to an anime when it seems to exist in such a temporary state. It shows up every 4 years for 10 episodes and then disappears again. 4 years is a lot of time to just stop giving a shit about something unless you decide to read the manga. Those endless 100+ anime might be unsustainable nowadays but they definitely did a good job at supplying a fanbase with a steady stream of shit for them to obsess over, even if it was just to bitch and moan about it.
