I wonder if the almost-sereneness which you mentioned in the previous post, with which the show gives itself time to explore its world, could be considered to be at odds with how it doesn't go into for example Kyoko's backstory. But I don't think so, because it's not that exploration with which the show is concerned, but stuff more directly--and forwardly, in what you also mentioned in the previous post as directionality to the narrative--relevant and powerful.

This is abbreviation, not distortion

I like that distinction! Or not even abbreviation: just not exploring side paths, which anyway leaves a lot of room for fanfic! :)
