Director-screenwriter Ben Wheatley brings a fresh mystery and bite to the hitman genre, although a deeply weird twist and buckets of gore may throw more than a few audience members.

There's no disputing the ingenuity and even the brilliance of this mind-bending mashup, which begins as a gritty recession-era marriage drama - the opening scene features a couple arguing about whether they have the money to get the Jacuzzi fixed - and then descends into ominous violence and finally total insanity.
—Andrew O'Hehir Salon
Brutal and bloody and utterly unnerving, thanks in no small measure to Jim Williams's brilliant score, which is filled with strings so taut, they sound like screams you might hear in the distance and decide (quite sensibly) to ignore.
—Chuck Wilson Village Voice
This is a far more brutal film than Wheatley's first, 2009's Down Terrace. Though it had crime at its center as well, it was balanced by a dry irony and far less blood. There is no offset in Kill List, with one scene so relentless in its gore that it makes the notorious elevator scene in Drive pale in comparison.

...offers some strikingly nightmarish imagery and a feel that's reminiscent of an earlier, grittier era, yet at times sharply contemporary.
—Allison Willmore Onion AV Club
That assured style is the spackle that holds Kill List together: when the plot doglegs into insanity, and the characters follow suit, this brutal fever dream refuses to fall apart.
—Jeannette Catsoulis New York Times
Banal at the beginning and preposterous at the close, the British horror film Kill List jumbles together wildly incongruous ingredients to create a dramatic mush.
—Kyle Smith New York Post
It's a road movie of sorts, like the Steve Coogan/Bob Brydon comedy The Trip, only with fewer expert impressions and more inept executions, but lovely scenery just the same.
