Indy Stunt Show wasn't open at Grand Opening. Indy Stunt Show opened in August of 1989 and Star Tours in mid December of 1991. From May to August of 1989, DHS only had Backlot Tour, Great Movie Ride, Monster Sound show, and tour of the working Animation Studio.
Star Tours was in '89. But still, shows how little it had, but was still like a full day when you took the full studio tour.
Having lived it and having participated in what (in 1989) constituted the Internet, there were a lot of people who felt ripped off by the opening of Disney-MGM Studios in the spring of 1989.
By 1990, after both Indiana Jones Stunt Spectacular and Star Tours opened, pretty much all had been forgiven.
Both were incredibly popular IPs at the time and went a long way towards healing the wound that had been inflicted by the original opening of Disney-MGM earlier in 1989.
I didn't make it make it to Disney-MGM Studios until the spring of 1990 and recall really liking the park. But I'm a sucker for 1940s Americana, America's "Greatest Generation".
My memory is foggy from what happened all those years ago, but I recall people (at least among those who posted) disliking Eisner after the price increases of 1985 & 1986, and genuinely hating him after the opening of Disney-MGM Studios in
early 1989.
Hey, what can I say? Even in the 1989, WDW fans were demanding.
Things were quelled in 1990 and, with the opening of Tower of Terror in 1994, we online were describing Eisner as the greatest CEO ever.
Seriously, Tower of Terror blew us away. To this day, it's still my favorite "new" WDW attraction.
Don't feel too bad if you missed it. Expedition Everest,
with a working Yeti, was almost as good. If you were among the few who saw a working Yeti, consider yourself lucky. It's the last exceptional attraction built at WDW.
Today, the "B Mode" Yeti pains me every time I ride Expedition Everest. So much wasted potential.
