Chicago Sun-Times by Richard Roeper

Joe Lynch’s fantastically creative, subversive and Tarantino-esque Mayhem stands alone as an entertainingly bloody and dark and twisted social satire — but it’s even more satisfying for those of us who loved Steven Yeun’s Glenn on The Walking Dead.

We Got This Covered by Matt Donato

Mayhem is a wonderfully violent middle finger to corporate culture, gleeful in its desire to redecorate cubicles with red blood splatters.

Variety by Joe Leydon

A smartly constructed and sardonically funny indie with attitude that somehow manages the tricky feat of being exuberantly over the top even as it remains consistently on target.

RogerEbert.com by Brian Tallerico

With his best film since “Wrong Turn 2,” Lynch channels that national anger into a stylish, smart, propulsive gore-fest set in a corporate America that takes no prisoners. But when did it?

The Film Stage by Jared Mobarak

Everyone involved grabs his/her role by the horns and rides the adrenaline rush to victory or death.

ReelViews by James Berardinelli

While this sort of film has its share of pleasures, it runs out of steam long before the end credits arrive. At some point just past the middle, it goes on autopilot. The glimpses of cleverness become less frequent and the movie seems more interested in upping the body count than advancing the (admittedly thin) story.

Movie Nation by Roger Moore

It’s a funny, bloody mess, but a polished C-movie that aspires to B-movie status.

The Hollywood Reporter by John DeFore

Though it's not particularly inventive, the film has a fine time pitting the office dwellers against each other.

Time Out by Daniel Gallant

Mayhem is an energetic genre flick that looks stunning and moves at a ferocious pace...But contrived dialogue and a bewildering narrative tarnish this otherwise enjoyable pulp effort.

Village Voice by Craig D. Lindsey

I’m sure the movie was made for Yeun (who also serves as executive producer) to finally have a chance to prove he has leading-man chops — and Hollywood should start giving him movie-star, action-hero gigs, like, yesterday.
