I was talking about it in general. Anything that has a focus on characters talking and living easy lives is not going to be animated as much as action-focused stuff. Obviously, there are some exceptions like Akebi, but something like Hidamari which is what OP posted or Joshiraku which jokes about it doesn't have much animation in comparison to the stuff I mentioned.
Aria is one of my favorite shows by the way. I don't mean this in a bad way.
