Review of High School of the Dead

I read all volumes of the manga before watching the anime. The anime basically features the first 4 volumes of the manga. I really like the soundtrack from Maon Kurosaki. What annoyed me a bit where the ecchi moments in some scenes. But all characters are very cool i liked Takashi and Saeko the most. However i can "only" give 7 out of 10 points. Of course Art, Story, Sound and Characters are great. But the Story is not really original. " A Zombie Disease breaks out. No One Knows what causes it and a group of Highschool kids and a Highschool Nurse(In a whole wehave 2 boys and 4 Girls)
are trying to survive in this "new world".
They later accept that there is no turning back out of this chaos and that they will only survive if they work together.

I know that the Anime was airing in 2010 5 years ago.
I hope that they will make a second season volume 5,6,7 are still missing.
But for this the manga will also have to continue.
