Walt Disney Animation has a particular ability in making their versions of fairy tales the "definitive" animated versions... I suppose there is room to argue there, but generally speaking, I don't think anyone is considering making a better version of "Snow White", "Cinderella", or "Sleeping Beauty" in animated form. Why isn't there more wiggle room for others to make their own version?
I think there is a sort of timeless, magical quality to some of their films. It's almost an indescribable factor. When you care so much about the characters, have drawn yourself into the fantasy of their world and situations, you want to believe in it. You aren't watching a film... You are living a story. And accepting that it's not the only version means accepting it's not real to begin with.
I haven't seen a lot of scenes from "Meet the Robinsons", but I am encouraged that Disney is getting back to this magical place where they once were. Where the impossible seems likely, and your dreams are just a song away. I am very hopeful that the best is yet to come... Especially since I'm pretty sure no one will want to fund my Frog Prince movie once "The Frog Princess" comes out!
