I personally think it’s a shame it’s not themed. The main appeal is obviously the size but just think back to when Colossus was built - the appeal then too was the size and the 10 loops, it could easily have been left with a tin shed station, a concrete pit etc a la Sik at Flamingoland. And same again for Stealth, its main selling point was the height and launch. The minimal 1950s American drag race theming elevates it from what could have been just a plonked generic white coaster.
Hyperia will be standing for the next 30+ years, I think it’s a wasted opportunity to build something that looks so bland and generic (and possibly even ugly with its cigarette butt supports). Once the hype dies down, we’ll be left with an unthemed coaster into the 2050s in a park that clearly does value theming, as we’ve seen what they’ve added to Colossus and Stealth this year. Even the newly refurbished toilets this year are themed more than Hyperia!
I just think it’s the long term vision for the park that has been let down with this project.
