Fair enough on the first point, I didn't feel like this series was pushing or sexualising yuri, however, it definitely shows a much happier world than what reality would be.

The series definitely focuses a lot more on the relationship of the 2 main characters than what happens in the world and what caused the world to be the way it is, which is fine for this series since its quite short, but I can see how that lack of world building and world exploration could turn some people away.
