I never said it did
It’s just an opinion, based on raising 2 kids. I KNOW what my children, and their social group, considered a kiddie ride, and thus beneath them. They would 100% consider that Mack coaster to be a kiddie ride and would have zero interest in riding it, and that’s even though both my kids grew up with HP and had me queuing at midnight for the books lol
From what I’ve seen of Arthur I would put it on a par with mermaid or phantom manor, or maybe even ET. How many 12/13 year olds do you see having a ball on those?
I’ve never said it had to be a scream machine for the Potter crowd. I’ve said that to round out the area it needs (imho) to be far more thrilling than that Mack coaster.
Here is the thing though, you are automatically thinking that the DC Replacement, if it is the Mack InvertPow, that it will be a clone of Arthur in layout. And that should be wiped away from thought right from the getgo.
The Mack Inverted Power Coaster, has only had two implementations of it's ride system in the world, the first being Arthur at Europa and the other being Dragon Gliders from Motiongate Dubai. And both, do have distinct and different layouts, that are tailor made to their environments. Universal has a lot of land there to flesh out the ride system, making it more thrilling than other versions of the InvertPow, while also still being a family coaster. And that with Universal wanting to flesh out the parks more, it makes sense to get a family coaster that can offer variety to everyone, and not just to one distinct crowd.
If you dismiss one option because of just one example, then perhaps the viewpoint needs to be widened out more.
And also, for those wondering; this is the official ride system page from the Mack website..
