Christmas Do-Over (2006) on Netflix

Plot summary

Kevin is a divorced music composer who spends Christmas with his ex-wife Jill's family, where Jill's father Arthur never liked him. He buys his son Ben's gift at the last minute and the package holds an easy bake oven. Only Ben and Jill's Granny Conlon welcome him. Jill's boyfriend Todd, a cardiologist, gives Ben a better present, plays Santa in Kevin's place and hands Jill a car. Kevin tries to leave town but a giant boulder blocks the road. At the fair, Arthur loses again to the neighbors. Dinner ends in arguments, and Ben wishes Christmas came every day. When midnight comes, Kevin is standing outside the house again as Christmas morning arrives.
