I understand the goal, but the only reason they are doing that is because they never really included SotS in the Disney canon yet somehow allowed one of their most iconic attractions to be based upon it. I personally feel, rather than sweeping something under the rug, it is a more-powerful statement to admit something is no longer appropriate and fix it. In so many ways and on so many issues, 2020 has taught us that pretending something didn‘t happen or is not happening does not fix a problem.
The $200 million it would take to redo two mountains would be better spent producing an updated SotS with a primarily African American cast and crew. They’d keep the iconic rides (presumably updated with the new actors’ voices), showcase black talent, have a story that actually makes sense with four drops, and make money from the film.
