Christopher Guest and his regular cast of improv legends tackle another unsuspecting target in this wild-eyed send up of the competitive dog show circuit. It's a bit more all-audiences than Spinal Tap, while completely skipping the emotional hooks of A Mighty Wind or Waiting For Guffman, but still delivers enough legit snickers to validate a simple retirement as late-night cable network filler.

The straight-ahead plot never shows much interest in progressing beyond simple character-driven adventure, and while each member of the cast is good for a smart punchline or two, the roles themselves are universally shallow, narrow caricatures. Fine as a background flick, thrown on to fill the air when your focus will be frequently elsewhere, it will never quite reach the same level as its siblings.
