Make no mistake about it, "Blue Collar TV" (7 p.m., WB) is a major departure for its network. Whether it represents a new direction or a sign of desperation remains to be seen.
A half-hour sketch-comedy series featuring the stand-up trio of Jeff Foxworthy, Bill Engvall and Larry the Cable Guy, "Blue Collar" has some impressive comedy credentials: the Blue Collar Comedy tour remains the second-highest-grossing stand-up act ever; the movie of the tour sold more than 2.5 million DVDs; and the "Blue Collar" TV specials have set ratings records on Comedy Central.
But the show is a bundle of contradictions. The "Blue Collar" tour was a stand-up smash, but this is a sketch show in which most of the sketches are flat, obvious, crude and invariably way too long.
