Next Day Air might have been simply a funny film if it hadn't been so bloody violent, several reviewers say. "The humor is there, but violence brings the laughter to an abrupt halt," writes Claudia Puig in USA Today. Several critics compare it to a Quentin Tarantino movie, but Peter Hartlaub in the San Francisco Chronicle says that the violence in this one amounts to "a bit of a buzz-kill, running counter to the strict stoner comedy vibe in the rest of the movie." Nevertheless, the movie receives some heavy applause from a number of critics. Nathan Lee writes in the Philadelphia Daily News "It's hard to make a movie that ends with blazing guns and dead bodies and still send the audience away laughing, but Next Day Air finds the right drive-in movie tone." Comments Nathan Lee in the New York Times "With a script that snaps, characters that pop, a blaze of streetwise attitude and enough firepower to pulverize a significant chunk of South Philadelphia, Next Day Air nears neo-blaxploitation perfection."
