This is likely Christopher Guest's most accessible mockumentary, with a bevy of adorable dogs in front of the camera and a significantly less amount of 'cringe' compared to "Waiting for Guffman's" "Gummo"-esque cast of outcasts. But that's no knock - while it may lack a certain subversive edge, it's no less hilarious or charming. Special mention must be made of the brilliant Fred Willard as the film's comedic MVP.
For a cultural juggernaut - such an outrageous level of influence on 21st century American comedy (and this one most of all because many characters receive the redemptive arch that cuts away the bite of so much American satire these days) -- Best in Show feels unassuming. Even humble. But no, this has designs on the world. We can talk about how evil those are, but it's hard to deny it doesn't perfectly execute.
Probably the funniest of the Christopher Guest movies, with too many brilliant performances to count. What's done to the characters can be disturbingly mean-spirited, but you have to expect that from a Guest film, and until the epilogue (which is just plain sadistic in some cases) it all rings true. Props to that poor Weimeraner for putting up with such awful (if hilarious) emotional abuse from 'mommy and daddy.'
