You can`t compare 1971 attractions - Pan and White (just about) - to a 1998 Tomorrowland attraction. Pooh dosn`t count for so many reasons, but the original line up with Mr Toad was based on far older DL versions. In custom built spaces of course.
Yes, Buzz is very popular. But how they though they could build cheap sets (even Dreamflight was more elaborate, If You Had Wings was more clever) as opposed to dimensional spaces and get away with it just shows the mindset of the management of that era. But you`re right..... a lot more could do with attention. A return of an updated AE and moving MI to the space formally known as the Galaxy Palace would work too. Funny that.... destroy a CV attraction to build a theatre, when there was one a hundered yards away that could be converted far more easily and cheaply. Not to mention actually gain an extra attraction for once.
