For me, this was always a matter of "when" not "if" a replacement would come to Splash Mountain. The origins/source material were not going to change. Even if the ride itself isn't inherently racist, the source material absolutely is. Our culture has shifted now to the point where efforts are being made to correct the mistakes of the past. Sacrificing a beloved theme park attraction is amongst the small "sacrifices" that white fans can make.
As I've said somewhere in the previous 116 pages, they can't skimp on this. You have a long attraction with plenty of great space for incredible show scenes. I want to see an AA heavy attraction but also include layering where appropriate (a la Na'vi River Journey). I'd love to see a Dr. Facilier sequence that combines AA's and special effects.
It's ok to miss the original, but the replacement has to be better and that hasn't always been the case. This is the most iconic attraction to be replaced (apologies to Horizons and Imagination) and they simply can't skimp on this.
