It was weird that we went from 1900s, 1920s, 1940s, to 1999.
It was weird when they did it in 1994, and it's even weirder now.
I assumed they were going to revert the finale back to 1960s to be honest, if they were going to *only* update the finale. But that would be hard with the voice actors deceased and the original ending being a different voice actors than the current one.
At the end of the day the decades presented in the 1964/65 Worlds Fair version of the show are exactly as distant to those audiences as the new decades for this upcoming version will be to us.
It has been 60 years, and this update will now buy them 60 more.
