A Kevin Smith DVD is not so much about the movie contained therein as it is about Smith and his cohorts, but they are as witty and engaging as the characters within the film are rude and uncouth, or perhaps it’s the other way around. In any case, the 2006 comedy was a return to form for Smith, who found a way to explore the maturation of a pair of characters that seemed, in their original incarnation about a decade previously, to be destined never to mature. The film’s comedy is no cruder than others of its ilk, and is at times rollickingly funny. The DVD’s picture and sound are nothing to get excited about, but Smith puts as much energy into his DVDs as he puts into his films, and the two-platter set quadruples the film’s pleasures. One of the three commentary tracks, featuring the cast, is as funny and outrageous as the film itself, while another track, on the technical aspects of the shoot, is exceptionally informative and insightful. Other features chronicle the film’s production in an entertaining manner and provide oodles of deleted scenes and similar materials. You don’t necessarily have to appreciate the movie to find what Smith has done with the DVD to be both rewarding and delightful.
