A large majority of so called "Christmas Movies" have nothing to do with the true meaning of Christmas. Half of them are about santa claus, yet are considered "Christmas Movies"Good movie but not even close to being a "Christmas movie". It has nothing to do with what Christmas is about.
Ok, lets assume for the moment that Jesus actually existed, the bible makes no mention that Jesus was born anywhere near Dec 25th and, in fact, seems to suggest that he was born sometime in the spring or summer. Combine that with the fact that many of the Christmas traditions we all know and love are paganistic in nature, I'd say the "true meaning of Christmas" is muddied at best.
