Terrible, definitely only for zombie movie obsessives.
I knew a girl once who was strangely obsessed with zombies/zombie stories. Even to the point that she carried around a "zombie kit" in the back of her car, in order to deal with any unexpected outbreaks. I am not joking about that either.
She's the only kind of person that could see any value in this un-funny tripe. And maybe people who will laugh at things just because they are supposed to be comedy, regardless if they are actually funny.
