An obvious "do-over" of Groundhog's Day, where a foolish man is shown the error of his ways by being doomed to repeat a day again and again (this time Christmas), until he gets the message and changes. This movie can be difficult to watch, unless you enjoy an anti-hero with no apparent redeeming qualities.
There's a vague parallel to Scrooge, too, except in Scrooge's case you rapidly learn that there's a great deal of suffering in his heart, and there is a good man locked inside somewhere. When confronted with the truth about himself, he repents, and changes. No such case in "Do-Over."
Why his ex and her folks put up with this vile self-absorbed slimeball on Christmas is anyone's guess. All he does is create trouble and make a jerk of himself, hurling sarcastic mockeries at anyone in sight. He shows no human feeling or positive qualities, at all. Why does his kid want him around? From action that occurs early on, you learn even his kid means nothing to him. Even when magic steps in and locks him in this endless cycle, he still doesn't learn. Instead, he exploits the process to hurt everyone even more. Naturally, he gets in fist fights with Christmas icons such as Santa Claus and a Nativity scene Joseph. His self confrontation process is painfully slow, if it occurs at all. It appears he manipulates events only for the selfish intent of escaping the do-over cycle.
The only value to the movie are the performances of the victims of this guy--they are really an endearing bunch of people, endowed with patience and kindness that gives the movie what level of Christmas cheer it does have. A nice cast overall; I liked all the family members. Even the actor playing the jerk is good; too bad the script didn't give him something better to work with.
If you find mean-spirited thugs funny, you'll find this guy hilarious. He makes Scrooge and the Grinch seem like Santa's elves by comparison. However, if you want a movie with a cheerful, positive Christmas spirit, see "Miracle on 34th St.," "Wonderful Life," or "Scrooge." But not this.
