I didn't watch the show. I read around 100 volumes of the comic, and quit at the rape scene. I kind wish I had stopped earlier.

I was very unimpressed with basically everything - character development, plot, action, "jokes", and the absolutely ridiculous amount of gratuitous sex. The main character and "hero" is nothing more than a Mary Sue and a heel. I can see tons of opportunities for whoever is adapting it for TV to cuck it up even more.
