Yeah I have to say I'm really disappointed in DHS...
I don't even mind if it's not a working studio anymore, that's beyond theme park business imo. But they have watered down or completely taken away a lot of the "studio" elements of the park.
I LOVED the Backlot Studios Tour and I'm really bummed it's leaving. It started to suck when they scaled it down for Lights Motors Action but I still loved the American Film Institute Showcase at the end =(
I also really enjoyed the American Idol Experience. It was always different and interactive. It was a cool twist to make real people the stars of a show.
The Magic Of Disney Animation... well it hasn't been the same in years. Animation is such an important part of the whole company that I think they should re-vamp this and make it totally cool.
I also loved when they had the exhibits for popular movie sets/props that changed every so often (the Backstage Pass thing). They could totally bring that back and it wouldn't be hard bc the stuff is already made.
The Voyage Of The Little Mermaid either needs to be revamped (the DisneySeas show is awesome!) or just replaced. An inside Prince And The Frog show would be cute and give that great movie representation in the park. Also, Beauty And The Beast is cute but it's old (and not that great once you've seen the Broadway version). I'd love to see them put in a Tangled musical =)
I really love Rock N Roller Coaster, Toy Story Mania, Fantasmic, and Walt: One Man's Dream. I would love to see them expand Walt and add some new scenes to Fantasmic.
