That's what you'll get if you watch this anime. Nothing more, nothing less. So if you enjoy watching zombies getting slaughtered and masturbating at the same time, this one is for you. If you want some depth or a well thought out story with some kind of point to it, go somewhere else. The same goes if you're looking for an actual horror series. For unless you're hemophobic or hate female genitalia H.O.T.D. won't scare you.
This lack of any actual horror and abundance of fanservice completely kill this series for me, which is quite a shame as there was potential. The animation is beautiful, the action itself is good, and the same goes for the voicing. As a whole though it's very disappointing, and I'm amazed it gets praised as much as it does. I've heard people mention it in one sentence with Mirai Nikki and I'm just baffled.
Now, the makers aren't hiding the fact that they were making cheap smut, and if you're really, really into that sort of thing then give it a go. You won't be too deeply disappointed. For everyone else though, don't bother. Just find some screenshots of the bathing scene via Google Images, and you'll get the exact same experience as anyone who watched H.O.T.D. did.
