A lot of art is unrealistic - that doesn't make it a fairytale.
Anyway, I'm not bothered about it being classified as a fairytale - but I don't think I'd put it in that genre myself.
I think it would be interesting to see what proportion of the people who have been to see it were women. When I saw it the audience was pretty balanced male & female. Of the frienRAB of mine who have seen it it's pretty much equal men and women, and the friend who raved about it the most was male.
