David Balzer of "Toronto Life", rating it three out of five stars, called it "a cool trip down teen dramedy lane, but one senses the film could be a lot smarter. Bartlett's drug selling, it turns out, is not the main subject of the movie; 'messed-up people' are, and this causes Charlie Bartlett to lean on psychobabble about disaffection that it initially tries so hard to mock. The film's use of Cat Stevens's anthem from "Harold and Maude," 'If You Want to Sing Out, Sing Out,' encapsulates its problems; instead of acting as a wry expression of Bartlett's dark philosophy, the song becomes the kind of pat message of self-empowerment that drives teens to Prozac in the first place."
