He didn't tear out Body Wars. Also, Test Track and Mission Space are classics. What would he have replaced SSE with?? What was behind the JIYI revamp??
I don't agree that Test Track or Mission Space are classics.
He wanted to fit something like rocket rods in SSE.
Other posters would know better than I the intricacies of JIYI but the gist of it I believe was Eisner wanted to replace it but Kodak didn't want to dump a ton of money on a new attraction, so what we got ended up being a significant downgrade.
