Executive produced by Edgar Wright—the guy behind Shaun of the Dead, Hot Fuzz, Spaced, and Scott Pilgrim vs. the World—first-time director Joe Cornish's debut is fantastically clever and relentlessly funny. Like all great monster movies, it's got bit of social commentary slyly poking its head out from the shadows; if you can see past the mangy, jet-black fur and phosphorescent fangs of Attack the Block's aliens, you'll find a fair amount to think about. But—again, like all great monster movies—if you'd rather just roll with it, and simply have a better time in a theater than you've had in entirely too long? That works too.
