My wife watches them and I like making her happy, so I watch with her, but I don't see why anyone enjoys them. They recycle the same themes over and over and at least one person cries in every movie. It's so predictable.
I prefer the old classics myself like, It's a Wonderful Life and A Charlie Brown Christmas. Oh, and I also love A Christmas Story where all Ralphie wants is a Red Ryder B.B. gun. They're all fun to watch.
