I think the nets are as aesthetically pleasing as possible. Though I'm not saying they actually are aesthetically pleasing. Lol.
I also think that either the other side of Rockit gets themed to Dr. Seuss, or they put in a Dr. Seuss facade behind the Trolley ride to block Rockit. It's not an eyesore at Universal, but in IOA in Seussland, I could vomit that image up. :/
