Most critics like it, and none dislike it outright: three positive reviews, five mixed, nobody negative. The praise clusters on the jokes, which several reviewers find funnier and more inventive than the usual gross-out stoner comedy, and on John Cho and Kal Penn, who are repeatedly described as a well-matched pair. Variety calls them a perfectly matched comic duo, and the film’s playful, pointed treatment of racism is counted as a strength by more than one critic.
The reservations are about evenness and familiarity. The Guardian finds dull stretches between the horribly funny moments; Empire thinks the toilet humour holds back a warmer, richer comedy; Slant Magazine, the lowest score, finds it hard to tell apart from earlier stoner films and is troubled by the White Castle promotion and the handling of Asian stereotypes. The spread is moderate rather than wide, from one outright rave to a shrug, and two reviews could not be fully read, so the picture is incomplete.
