That’s not the lesson. It’s not an issue of budget. You’re denying different typologies and trying to declare them the same.
It is often an isue of budget and pleasing more than just the immersion hounds.
There are different auidiences.
If every land was as detailed as Tokyo's Mysterious Island I would love so much of it. But diminishing returns. The reality. There is always a balance even if designers and producers got blank checks.
Parks know that is not sustainable. That is why flaws will be evident. Due to different schools of thought and resources being finite(budget and otherwise)
Gotta please more than one market to stay in business.
I think Untrainable Dragon has all the show writing elements, the character property and enough of an immersion to please the majority of all the reasons people come to a theme park. In a perfect world, after continued success they will continue to improve everywhere. *shrug*
The fact that The Untrainable Dragon exists, a show of its scale in the park (as well as another show of large scale in the park) exist for daily operations in this day in age of designing themed entertainment is great as it is not common.
As a whole, the teams balanced it very well to exist as an extension of a land. I rather this than just a theater in a park that shows a show that does not fit where the theater in the park is located with show writing theme and full attempts at fitting in the area in the other disciplines. That to me, is a reason as a whole it is superior to Nemo in Theater in The Wild.
Theme Parks are of the five senses and emotional catalyst storytelling, not just visual. In a perfect world each aspect would be a blank check. I however, feel Untrainable does this better than Disney's indoor show ventures. There are not many indoor stage show at Disney that have existed in recent decades that attempt this. Even Studios, who has been trying to get away from the Studio Park throughline goes back to Mermaid just being a show in a box for convenience. The Villains show probably similar. No attempt at a tie in to where you will enter the show from being evident thus far.
Nemo hits none of these other than Nemo is an animal, but why Dinoland(now defunct) Asia(no attempt) and ultimately an entire new project area is not currently showing any attempt at enhancing what is outside or inside.
