Although this already has a thread, it is all of one post and has the fandom bullshit we try to discourage here. Also, it's a review that spoils the absolute fuck out of an admittedly predictable show, so I don't know where to go with this.
Still, whatever, opinions time. Frankly, the anime sucked massively, being a typical harem-shit anime with a wimpy protag who does fuck-all but get chicks for absolutely no logical reason, pervy moments everywhere, and a plot which is paper-thin. The manga executes every single element in a superior manner (and actually develops a plot that can hold water), and Tsukune actually does stuff that isn't cowering behind said chicks.
tl;dr: Read the manga and ignore the anime unless you just want panty shots, breasts, and mindless fanservice.
