I don't think anyone necessarily likes seeing the main protagonist getting wailed upon. I will say though, I appreciate how much physicality this show lends to its female characters. So often women in fiction are the spellcasters, ranged fighters or if they ever take a hit are knocked out in one blow. I really appreciate that they let Ryuko really DISH out the pain but also TAKE it as well. It's something I've always liked about some American comic book super heroes like Wonder Woman and She-Hulk. They get their hands fucking DIRTY (which necessitates that you take some hard blows yourself) and the combat is so visceral. I feel its very anti-sexist in a way and that make me cool with it (assuming there is an appropriate give and take of course).
