Reality TV's most fertile brood -- the Duggars of Arkansas -- trek to wintry Colorado for their first-ever attempt on the ski slopes. (Dad Jim Bob leads the trip while his wife, Michelle, stays behind to take care of baby Josie, who is still on the mend after a health scare.) Fans will find well-trodden territory, such as a familiar packing scene (200 shirts? check!) and wholesome family fun time. But it's refreshing to see a grounded, good-humored clan get along.
