Description from the So Bad It's Horrible page at TVTropes:
"Christmas in Wonderland is a 2007 Christmas movie with an All-Star Cast, apparently zero script, and exists solely to piss off the entire population of Edmonton and Canada in its sight. Its main selling point is that 90% of it was shot in West Edmonton Mall (formerly the world's largest) in Edmonton, Alberta, Canada... yet when it's not being a 100-minute commercial for West Edmonton Mall, it's trying to justify its plot by relying on the seminal characters being ten times as moronic as families in average family Christmas films. To make a list of all its inconsistencies would be writing a list as long as the script itself — for example, the opening credits are supposed to be in Los Angeles, yet it's obviously shot in Strathcoma in Edmonton. The two boys apparently hate Canada, yet they have strong Canadian accents. Furthermore, the mall itself is made to look like a magical palace on the exterior, with puke-worthy results. That's only the beginning. The film's an insult to Edmonton and Canada, and the one cinema in the mall that showed it in 2007 dropped it after a week because it's so bad. And boy, Patrick Swayze looked horrible; this is not a film you'd want to remember him by. The fact that in this movie, there is no snow anywhere in Edmonton at Christmas sums up how little they cared. "
