One plot hole I can't overlook
I was watching this with my girlfriend last night, and we don't usually mind the obviously overly dumb characters, such as Jack Frost barely fighting back at the end, to get his Santa coat back, or the grandparents who are blissfully unaware of any reason that Tim Allen suddenly changed so much, and how all of Canada is full of ONLY kids, or anything else like that. The only problem she and I had was at the end, when Tim Allen got control of Santa again. Wouldn't defeating Jack Frost have put him at least a day after where he was when he lost control of Santa for the first time? Since it transfers the people who fight over being Santa to the exact point they'd have been at when the Escape Clause was used, once the coat has chosen a host. That kind of logic annoyed me as a kid, and it annoys me now.
Begin the "it's just a kid's movie" replies now :)
