“The anime itself doesn't shine in any specific category, and probably some (few) parts/elements are "broken", but all in all it's warm/positive/funny. I didn't like much the first episodes but there weren't any hard reasons to stop watching it so I kept going => I didn't regret that decision - at around the first quarter I started liking it. The last episodes are, in my opinion, superfluous.”
