Oh totally - that comment wasn't pointed at you, it was pointed at whoever came up with the concept and whoever decided it needed financial backing (and maybe a little bit at the people who do think Disneyland needs a new look for its Space Mountain).
I personally think the 2005 redo did a decent amount of good, but I'm also of the opinion that Disney seems far too willing to let Space Mountain fail to live up to its potential. When it comes to Disneyland's E-Tickets, I feel like Space Mountain has always kind of been "doing the least" and yet everybody fawns over it. The concept is great, but the execution is mixed, and the popularity hasn't budged. This feels true for pretty much all the Space Mountains worldwide, to varying degrees - though Paris' original version was basically unimpeachable in its marriage of concept and execution.
Point being, I think there's plenty of room to improve Space Mountain, but when I see Tokyo putting so much effort into changing the outside it makes me feel like someone misunderstood what actually needed some love.
