Jeremy of The Daily Rotation wrote, "Oscar-nominated director William Friedkin‘s NC-17-rated Killer Joe is as dark as they come. The film walks a fine line of being brutally graphic and unsettling one minute and then mostly hilarious the next. Friedkin’s direction is calculated and helps the grim script (written by Tracy Letts) grow into an untamed beast, full of sleazy and unlikable characters. The real show-stealer is in the performances, led by Matthew McConaughey and closely followed by Thomas Haden Church, Juno Temple, Gina Gershon and Emile Hirsch. Killer Joe is a repulsive tale of killing and backstabbing with hefty helpings of good old fashioned Texas deep-fried chicken."
