I think that pretty much every form of fiction (I’d include fantasy, obviously) can actually be a real escape from places where you feel bad, and from bad places. It can be a safe place you go, like going on holiday, and it can be somewhere that, while you’ve escaped, actually teaches you things you need to know when you go back, that gives you knowledge and armour and tools to change the bad place you were in. So no, they’re not escapist. They’re escape.
