Disney's imagineering group is huge, and until the remake of Test track I never really noticed the difference experience can make. (Don't get me wrong, TT came out okayish, but the old version had more energy to the atmosphere). It's clear to me now that there's an A team and a B team, perhaps even a C team, for stores, landscapes... little jobs.
I'm not complaining, DHS needs this so bad, but is anyone else get the feeling that the imagineers on the job for this are the newer kids on the block, the B team? Not because of child/toy theme as much as that it's as though they were given the examples that have already been done in other parks to improve upon, one of which was a ride design that was already built out, and just needed a re-theming. The senior imagineers stepped back and told them to "have at it kids, but here's the toolbox you have to keep to" (size, budget, materials, etc)
