After Shaun of the Dead, Hot Fuzz (a movie that deserves a sequal more than any other film, ever) and The World's End, I'm willing to watch anything Nick Frost and Simon Pegg put in front of my eyeballs a go.
Slaughterhouse Rulez looks like more of the same sort of violent whimsy that I've come to expect from Frost and Pegg. That's just fine by me.
