Mayhem could easily have been a one joke film and found itself with nowhere to go. It is a credit to director and cast that it keeps on giving – and for people in jobs like Derek’s, delivers a particularly satisfying cinema experience.

If there is any viewer discomfort involved in following our protagonist through a high bodycount toward his ultimate business goals and moral centre, the beauty is that [Joe] Lynch, like Derek, ultimately turns all this explosive depravity into art.

A fast, entertaining flick, and a fun entry into Lynch’s growing body of work.
