It reminded me an awful lot of “Shaun of the dead” which distracted me throughout the movie with thoughts of how to spoof it, But… I liked it. Only the good movies are worth spoofing. And I did like “Dawn of the dead”, so “Shaun of the dead” was good. Granted they are not mutually inclusive: A good movie can have a bad spoof (not looking at any one in particular, Scary Movie [all of them]!), and a bad movie can have a good spoof. I can’t think of any examples for the latter.
