I love this movie :D
It's such a sweet story, and clean enough that you can plunk little kids down in front of it and not have to worry about them seeing or hearing anything bad.
My family has this on DVD, and we now watch it every December. Dad even likes quoting from it, hehe. He was a little kid when this came out in 1964, so it's understandable that he'd have good memories of it from his childhood, as do I.
