I think a fanbase should have a little entitlement, honestly, depending on what's going on. Like when George Lucas kept fiddling with the original Star Wars because effects were better and removing the old ones? Fans were entitled to be upset about it. That's more ruining someone's childhood than doing a live action movie about a cartoon made about toys.
No matter how entitled people get about a Mu* though, I doubt they will just jump up and hug someone running a game like they will with a celebrity. One of many articles about how celebrity is not consent. But that's how fan entitlement can go bad.
On the flipside, I've hate-watched shows that I had started out loving, not because I thought the show owed me something, but because it went so off the rails. But some "fans" hatewatch because the show isn't doing what they want. And at that point, how can they really say they are a fan?
