In what delusional universe do people go to anime for a realistic experience? Anime has always been exaggerated, dramatic, bombastic, and a hell of a lot of fun.

An anime only needs to stay consistent with the rules of its own world to retain immersion that is as close to realism anime ever needs to be.

I still haven't seen KnB myself because action-packed sports shounen is exactly the opposite of the anime that appeals to me right now. But I am aware of how good it supposedly is, so I'll have to get around to watching it sometime.
