his comment is effectively constructive criticism. stop marking him out to be such a terrible person for criticizing something that someone has authored. no work is immune to that, and creators don't deserve our "positive energy" if their creations, in our eyes, leave something to be desired. you don't get praise just because you created something, nor do you deserve it.

please don't defend thin-skinned creators, and also please don't speak for them when you don't know or understand their intensions.
