I think once upon a time that all of our parks were filled with real, genuine Australian can-do spirit and put passion and pride into doing big ideas on shoe-string budgets (and showing up the big players in the process.)
There's that story of Lassiter's Mine costing 3 million and Disney Imagineering folks saying it would've costed 20 million. There's another similar story about Gum Tree Gully at Dreamworld. And then I think about rides like Bermuda Triangle and how cool the Pepper's Ghost effect was even as an adult and how so much of that ride would still hold up today. Same goes for Police Academy. Genuinely funny, really good stunts, brass-ring winning show. Same goes for Steam Trains. Super unique and a part of Australian history. Same goes for the Batman Ride - beautiful themed set pieces, awesome embark/disembark procedure into the simulator pods, totally mind-blowing stuff for kids.
Really unique ideas executed well that are over-achievers in their own right.
What happened?
I think OH&S plays a part in some ways for sure, but as @joz eloquently painted the picture above, somehow all of our parks got into this epic death of creativity through a thousand cuts and two decades on it shows. Every park has big, obvious SBNO crap somewhere. Facades that have no place in the "themed land" they exist in. Unkempt gardens. Lacklustre theming. Just yikes all round.
Take me back to an era where creatives created, not execs.
