Interesting viewpoint - of course thats a pretty subjective take on it. I'd rather you put it differently:-
"The kind of fantasy I like is about light and happy joy, joy because the real world sucks"
Which is fine for some - however I'm pretty much the opposite direction - I prefer fantasy that is dark and horrible and I'm far more interested in fucked up views on things.
Mainly because when I return to the real world it doesn't seem that bad.
All my favourite fantasy series are prettyy messed up, even Tolkien who normally gets accused of being 'safe' - The Children of Hurin is far and away his best story, and it's wretched!
Anyway my point is that just because someone likes a certain flavour does not mean that it's 'junk'.
What about Stephen Donaldson? Thomas Covenant is a wretched bastard, but it's one of the best series ever.
And what about other art? Films etc? Irreversible is probably one of the best movies ever made, but it's absolutley HORRIBLE to watch. But it had a profound effect on me.
Absolute nonsense. It is the crux and raison d'ĂŞtre of Jaime's character arc - without it he wouldn't HAVE a character arc.
