I didn't mind the censoring in Rosario to Vampire Capu 2. It wasn't supposed to be hentai (in which case censoring is annoying), and the way they did it fit well with show: using bats and pedo bears. I think it even made things funnier sometimes.
Btw, Rosario to Vampire was a good dose of well made ecchi+humor; in other words, the perfect cure for a case of having-watched-School-Days.
Just saying.
