This one could get lengthy. Christmas movies are probably one of my favorite genres of movies and I have several to get me into the spirit.
My all-time favorite Christmas movie has to be
My mom and I would watch this together every year. If it's on TV, I watch it. I had a DVD in college and lost it, so last year I had to seek it out to replenish my stock.
Other favorite Christmas movies are (in no specific order)
A Muppet Christmas Carol - this is probably my #2 favorite Christmas Movie.
Little Women - the 1994 version with Winona Ryder
A Christmas Story - which, I had never seen the full movie until a few years ago. I always watch the 24 hours of A Christmas Story on TBS, but I always came in at different spots and never saw the full movie. Brian had to remedy that since it's his favorite Christmas movie.
