Where you, the rider, are hit by a train and go to Hell. I’m in my 40’s and still find that a bit too dark. Or how about the Country Bear Jamboree, where the dismembered taxidermied heads of various animals sing to you? Not to mention the entire ride that’s about death, and begins with narrator hanging himself from the ceiling…
Anyway, Disney changes stuff all the time. I spent 30 years in California going there more or less annually. Probably the only reason this even warrants a mention is because it’s such an iconic ride. No one complains when they change the cars in Autopia.
