Go watch this show.
I am a total Zombie fan, and this show is amazing. From the very beginning the action grabs you in the bowels and rips them out. Everyone needs to learn that in a zombie apocalypse, you have to destroy the head. We learn how violent and disgusting that can be in the first few minutes of the show.
After a rip roaring beginning it slows down for bit to give some character development. Then the blood begins to flow again.
The reason I love zombies is that you can live if you do not do something stupid. Most of the students promptly show us how stupid they are by fleeing in a disorganized panic. They get eaten and become the first threats our heroes must face. There is a delicious plethora of people dying. We see friends betray each other, others breaking under the strain of it all, and students just getting killed in class. They have distilled the most powerful moments of a zombie movie and crammed them into a 30 minute show.
One thing that does not fit is the fan service. The extreme blood and boobs do not match very well. Being horny will get you dead. The female characters appear to be made of jelly, and Japan has some very loose rules with uniforms apparently.
Another thing I love about this show is the zombie type they used. They are the slow mindless drones that just kill. So a fast walk and being aware will get you out alive.
I wonder how they will do a how season of this but I am loving it. Also the sound track reminds me of 28 Days Later. WATCH THIS SHOW. Also keep watching after the ending credits.
