The breezy bullshit attitude is rank, stifling, nauseating. I know — how else would you play it if you were an actor hired to be in this stupid thing and everyone else was saying their lines, like, “ironically”? You’d have to go along, right? There’s only one way to perform in a zombie spoof, and that’s to adopt the attitude of an actor performing in a production of Hamlet at the Old Vic.
