I had no idea Peter Pan was a flop. This is my favorite version. I think because it is so much closer to the book than other versions, and also, it reminded me of the original play (the one where Peter is played by a woman) which I loved as a child.
I remember taking my younger cousins to go see this in the theater. The scenes were so beautiful, especially the skies. It just felt very magical even as an adult. I still love this movie.
