I mean, I would not mind the disdain if the actual result was good. Alas, we still don’t know so people have the right to be worry about it, specially if the main actress pulls “bunch of perverts” card.
This is not a cosplayer going to a fan convention, but a professional actress in a TV adaptation. This shit goes beyond “fake fan” shit takes. I don’t mind she is not a fan, I can be worry of the actual quality of the show if everyone is showing disdain about the source material. Is not a complicated concept to understand.
