I sympathize with the OP. In fact the behind the scenes/ classic Hollywood/ making movies theme had a huge influence on my son and is one of the reasons he graduated as a film maker and is producing videos today. We loved that feel of the park and being part of making movies, even if it wasn't a working studio anymore.
But it was also very apparent that they had basically decided to neglect the park and do anything to modernize or keep up the theme. The shows are very outdated. The backlot tour should have been updated instead of essentially allowed to rot away and close piece by piece. The Streets of America were basically left alone to sit and offer nothing to visitors except at Christmas. and the idea that it was a place you could experience the magic of making movies was allowed to be ignored or disappear, piece by piece.
Sadly, even worse in my opinion, is while I like the new additions in Toy Story Land and Star Wars, they really don't fit into any sort of overall cohesive theme for the park. Whereas Animal Kingdom focuses on animals and wildlife around the world (and in others in some cases), Magic Kingdom's overall theme is "fantasy" and Epcot was a perennial World's Fair, Studios is now a hodgepodge of things that aren't related to each other and it's hard to see how they fit together anymore.
While we'll enjoy individual attractions and areas at the park, all of us miss the Studios of old, and which that Disney had cared enough to keep it updated and done new things with it instead of ignoring the park. As someone pointed out with the quote from Eisner, what he said at the park dedication doesn't really make much sense anymore.
