Seeing as this is an old thread, it is time it was re-visited.
The tradition we have had as a family is when our lads were little would watch a Christmas movie each evening. All lights would be off except Christmas lights, popcorn and tangerines would be deployed and movie would commence.
This continued for many years, then the boys grew up and moved away but each time they come home (now with their kids), we all gather and watch at least 1 or 2 Christmas movies as a family...
If they have many more kids, I may have to rent a movie theatre.......
