||Finally a Christmas movie that invokes one of the best-known yet least discussed holiday traditions: regifting. If nothing else, "Christmas Do-Over" is "Groundhog Day," sloppily rewrapped and presented with less flair and good will...There is a bit of nice casting with Adrienne Barbeau as Daphne Zuniga's mom. But soon after horny, alcoholic grandma mistakes her gift of earrings as pasties and Jay Mohr's character punches out -- in succession -- Santa Claus, Jesus and Mary, things pretty much fall apart...Scribes Trevor Reed Cristow and Jacqueline David don't supply much to root for. Mohr's character is such a dislikable, nonresponsive parent and ex-husband, that his transformation from acerbic and smug to slightly less acerbic and smug just isn't that moving...The notion that one day can truly make a difference in life is worthy food for thought this time of year. Digging a little deeper, though, is a disheartening subtext that seems to say that if a woman just sticks with the mean and selfish guy, eventually he'll figure it out. Other notions of good will are also hampered by the supposedly heartwarming holiday ditty that marks Kevin's redemption. It's memorable mainly as the worst display of TV lip-synching since Ashlee Simpson.
