But they don't stop watching it, their identities are invested in it. There's sunk cost fallacy going on there. They don't want it to suck, they want it to keep getting better. And it doesn't. And they complain. But they keep watching anyway. I know a guy that watched every episode of discovery, complained how bad it was, then watched the next one. It didn't matter that it sucked, you can't miss knowing the canon!
They're entirely captured by the corporations that produce this stuff. Their minds are trapped arguing over the validity of literal nonsense because it's profitable to some company for that to be the case.
