Song of the South was a fairly successful film 4 generations ago. It's been probably close to 30 years since the general public has ever even heard of Song of the South, probably closer to 40 since anyone's ever actually seen it (aside from a few Disney fans, including myself, who bought a bootleg copy from ebay :lol
. Heck, I'd bet the vast majority of guests who ride Splash Mountain would assume the characters are completely unique to Disney theme parks and didn't come from a movie at all...
I agree Song of the South and Darkwing Duck have little in common. That said, both were great ideas, both were executed rather well, and both have fallen into limbo, and that's why the argument is always made. Bc really, Splash Mountain (or Zip-A-Dee River Run if that's what you prefer :shrug
is the perfect example of how a successful attraction doesn't need a movie/TV tie-in that everyone remembers or loved, rather, all attractions need are great characters, imagination, innovation, and a little love ever 5-10 years.
