I'm not one that believes that exposed coaster track is ugly, but it has to be implemented right. Manta at SeaWorld Orlando, for example, is integrated into the park beautifully. Hulk looks aesthetically pleasing over the lagoon. Dragon Challenge, on the other hand, was not an aesthetically pleasing coaster. While it didn't interrupt the immersion of Hogsemeade too badly, anywhere inside the exterior queue was a view of a massive entanglement of steal over a gross, murky retention pond with weeds all around it. Riding it and looking around also completely killed any possible immersion as you could look down and see that Hogsmeade Station is just a box or ample views of ugly backstage and the surrounding non-Universal property area.
