Of all Christopher Guest's partially improvised comedies, Best in Show is, well, the the best. The film's depth of characterization elevates it beyond the comedy of Guffman, which is mainly rooted in the characters' lack of self-awareness, into a sublime combination of the ridiculous and the heartfelt. When the film ends, you want nothing more than to continue following the various characters and their deeply rich plot-lines. It's a film that rewards repeated watching: highly recommended!
