Dead Wrong about "High School Of The Dead?"

I spent a portion of New Year's Eve watching High School Of The Dead with Hubby Christopher Wanamaker.
I decided to watch it again today just for the "hell" of it!  LOL!!!!
The broadcast series High School of the Dead (2010) opens on an ordinary day at Fujima Academy in Tokyo--until hordes of zombies begin attacking people. Anyone who's bitten by them is either devoured or turned into a zombie. Sophomore Takashi Komuro, four of his friends, and Ms. Shizuka, the overendowed school nurse, fight their way out of the school and struggle to survive in a world gone mad. Using swords, baseball bats, and an arsenal of high-tech weapons and vehicles, the teenagers beat, blast, and flatten their grisly foes. The cause of the zombie plague is just one of the many important plot points that's never explained, but director Tetsuro Araki isn't really interested in presenting a coherent story. He keeps the camera looking up the girls' skirts, down their blouses, or at blank walls that get splattered with blood. In one shot certain to go down in fan-service history, he follows a projectile over one girl's breasts and under another's skirt--in slow motion. Hormonal adolescent boys who enjoy the juxtaposition of jiggle shots and blood baths are the obvious audience for High School of the Dead; other viewers should approach it with caution.   Needless to say, this is one anime that is definitely NOT FOR CHILDREN!!!!!!!!!!!
Honestly, it reminded me of the 1968 film classic, Night Of The Living Dead. However, unlike its classic counterpart, High School Of The Dead  does not blame the zombie attacks on nuclear radiation waking the dead.   As I stated before, no obvious explanation was offered for the events that unfolded during the anime. Though,  self-proclaimed genius Saya Takagi suggested that the cause might be a pandemic!   Of course, there were some characters worth mentioning.  The school nurse, Shizuka Marikawa,  was an idiot, and Saya Takagi  is bossy and conceited!  At least, in my opinion!  On the upside, Monica Rial, my fave voice actress, had a  role in this particular anime--that of  Shizuka Marikawa.  Also, Jessica Boone, whom I loved as Misaki Suzuhara in Angelic Layer, voiced Rei Miyamoto in High School of the Dead! (Incidentally, Monica Rial also provided the voice of Tamayo Kizaki in Angelic Layer!)   Aside from no logical explanation for the events that unfolded throughout the course of the anime, the ending was inconclusive.  Does this mean that a second season looms on the horizon?    If it does, I'll probably get it just to see how the story ends!!!!!!!!!
