I've been holding back my comments on the banners, but man, I agree. They look like fan art.
The area needed some color variety, and what we see in the film would be perfect. Nothing about this looks like Jurassic World - rather, it all almost looks like a brutalist reimagining due to the shapes and colors. The makeover of the park is all greys and blues, and it's just kinda oppressive and ugly looking... and then you look at the film, and the park doesn't have those colors at all
