I don't think he could have left the collapse of civilization and everyone's death vague or an unknown like in Zombieland (or even L4D) with the scope of his story, but his description of it is bonkers and is so wacky that it just doesn't satirize military or government incompetence very well.

But then it could be forgiven if the rest of the book was half-way decent.

I kinda hope the movie is so ridiculous that it ends up in Red Dawn land, only without so much nationalism and more bone-headed action. Or go full-insanity and make it like Starship Troopers. Heh.
