Ooooh, I've always liked the animated one. Very hard to find. I've watched it maybe 4 times total my entire life. At this point I don't have or know exactly where to find a copy, but would be interested in finding one not too far down the road. It was a good telling of the story, and the animation and characters and music were really cool from what I remember.
I do like the 2005 version. I didn't care too much for the BBC version. One of the main things that bothered me was the girl who played Lucy. Buck teeth, and quite often went about with her mouth hanging open. Mary Poppins would say: "We are not a codfish!"
