Are we really pretending that the 5th dimension scene is something special that it elevates it so far beyond the other ToT versions?
I think it's appropriately strange. :shrug:
But I don't know that anybody's claimed the 5th Dimension is the only reason it's the best version. The ride is the culmination of the theme and design work of an entire land in a way no others are (or were), just for starters.
