I think Primeval Whirl was inspired by the iconic Palm Springs Cabazon Dinosaurs and enhanced with a carnival road side spectacle.
It's just like taking a road trip and seeing nothing but corn and wheat for hours or even days and then you come across something totally out of place and unexpected but fun.
People seem delightfully surprised when they see Dinorama. It's tacky but fun. The only exception is kids reactions when they can't ride Primeval Whirl. I have seen some serious tantrums. LOL.
Back on topic, thank you to all the contributors here. So, it appears that Epcot is getting GOTG coaster, just not a flying coaster.
I'm glad that TOT is spared but still super cautious on how Disney plans to execute this.
