I appreciate your sharing that with me... I love shooting zombies! ;-)

I read a review that put all sorts of socio-political-blah blah into it.
It's Fiction. The Zombies are the bad guys. The good guys (after they get their #$#@!$ together) take them out. There's some interestingly commentary on evil capitalists and incompetent bureaucrats and yadda yadda yadda. But it's easy to skim those parts. :-)
Like I said...it doesn't bog you down with a lot of details.
