I know I posted about REEEEEEEE:ZERO not too long ago, but I have similar questions with Dragon Maid and its popularity too. I do not have anything against it, but I do not find it extremely funny. I tried to find reasons why it is a show with a rating higher than Space Battleship Yamato and Galaxy Express 999, or for a more fair comparison, then stuff like Doujin Work (a much funnier comedy) or Taruto (being cute)?
Additionally, the sexualization of Kanna makes me feel weird. It is like BnP stuff, except with a dragon.
Cute lolis doing cute things.
