New comedy incoming! Just when everyone thought "Doogal" set the lowest bar possible for a dog comedy, here comes "The Shaggy Dog," a pointless remake of the 1959 Disney classic.

The comedian Tim Allen picks up where Dean Jones left off in the 1976 sequel, "The Shaggy D.A.," here playing assistant district attorney Dave Douglas, a careerist and dog-hater, who, through a series of mishaps too ridiculous and tiresome to describe, is injected with the blood of a 300-year-old dog. When Douglas himself turns into the fluffy dog called Shaggy, he discovers that he may not be a bad dog, but he has been a terrible husband and father.

Directed by Brian Robbins with zero flair or humor, "The Shaggy Dog" is a nasty, unappealing Tim Allen movie, whose comedy derives only from foolish stunts (Allen running on all fours, Allen lifting his leg to urinate, Allen catching a Frisbee with his teeth).
