I indicated that they shouldn't have based Splash on SotS, not that it shouldn't have been built. A different film should have been chosen.It still seems pretty drastic to suggest that they should never have built the ride at all. Even though I know its time to swap it out and acknowledge the problem, I do still enjoy Splash Mountain on some level and I will definitely miss it.
I do disagree that brining more attention to Song of the South would have fixed the problems with Splash. With such a depth of stories on the bench, I don't see how propping up Song of the South or trying to contextualize the characters is worth the effort, at least from an entertainment prospective.
We wouldn't be in this position had Disney chosen a different movie.
