A quick search of the internet will tell you that It's a Wonderful Life is the greatest Christmas movie of all time. Seven of the eight lists I checked list it as number 1. The outlier, Rotten Tomatoes had Meet Me in St. Louis as number 1 and Wonderful Life all the way down at number 10. I will admit to this small group of close friends - I have not watched It's a Wonderful Life all the way through. I have seen enough but it never really interested me. I also have never heard of Meet Me in St. Louis.

There are remakes - there are two versions of Little Women in the top 10, there is The Bishop's Wife and The Preacher's Wife; there are sequels Santa Clause 2 and A Christmas Story Christmas. There are horror movies, comedies, romances, even two that came out this year - Spirited and Guardians of the Galaxy Christmas. I have not seen those yet.
