An admirable low-budget slasher spoof that brings in big laughs, but at a slender 89 minutes it’s overlong.

The central premise is inspired (hill-billies mistaken for serial killers by college kids; misunderstanding perpetuated when kids get themselves killed) but not really feature length material. Deviations and new plot threads are jarring, no matter how early they’re introduced, and the final act is markedly different in tone from the hilarious first half – darker (and absent of solid jokes), but no less silly.

Speaking of jarring, the editing is occasionally sloppy. It’s not Raiders bad, but there are some key moments that are lost in clumsy ambiguity.

Still, Tyler Labine and Alan Tudyk put in downright brilliant performances as the central duo, and the initial set-up and execution of the premise is slightly patchy but nonetheless wonderful. It’s been a long time since I’ve laughed as hard as I did throughout that first 45 minutes. Throughout.
