When I heard that our favourite scumbag teacher was going to be voiced by Kittan, I was intrigued. Obviously, he wouldn't have gotten the part if he couldn't do it, so I was pleasantly surprised when he pulled it off so well that the scumbag came across as both an absolute bastard AND a total badass.
Now for the episode: I was pleased when the team decided to stop it with the nurse's sound effects, and I'm sure many of you are as well.
I actually predicted (Incorrectly as usual) that this episode would end with the scene in the petrol station, but looks like that'll take place next episode. I'm just impressed that by the end of episode three, they've only just started chapter three: Episode two ended half-way through the second chapter, yet it doesn't feel like they've thrown in a load of filler or extended anything: the pacing is absolutely top-notch.
So, at this rate, it's going to continue into a two-season anime, which would be completely awesome. I've already read the manga so far, and I can tell you that this is easily going to be heralded as one of the greatest anime over the last decade. In fact, from the first episode alone, the anime ranked, even to a friend who hadn't read the manga and had to deal with me over-hyping the anime, the first episode ranked up with the entirety Death Note, Gurren Lagann, and the first FMA series. At three episodes, it is ranking up with Brotherhood, Black Lagoon, and Cowboy Bebop.
Maybe I'm just a fanboy, but I know that I'm not biased because of the zombies, considering how I normally hate horror. I just can't wait to see if this anime (and manga) can out-do the Gantz manga.
