Escapism Real Quick

 Narratives are escapist when they have unrealistic psychology.

 Narratives aren't escapist if the characters have verisimilitude.

 I have enjoyed many harem comedies. However, the idea that these girls are attracted to that (using the term loosely) man is laughable in all but one case. This is escapist fantasy.

 Of course, stuff like Ergo Proxy and Aeon Flux is also escapist fantasy, albeit depressing instead of cute and fuzzy. "A bit of the worst of both worlds for ya."

 Dark Souls is way further down the scale on escapism. "If the giant dragon bites you, you probably can't just cast healall and fix it. Usually you die."
