Normally I don't have an issue with unthemed exposed coaster track. However, Rockit, like Dragons, is an ugly coaster. It throws off the forced perspective of the New York facades, it's in dire need of a paint job and a new banner, and it contributes to the trashy look of the entire front of USF. It also has an excessively loud lift motor so the entire front area of the park hears a constant motor noise. Oh and the playlist hasn't been updated since it opened in 2009, even though that would be the easiest thing to do. I would not mind if Rockit was removed for a better coaster.
Dragons was not a themed coaster, only the queue was themed. The coaster itself was a tangled mess of steel over a mucky pond and no landscaping. Compare this to Montu, which actually dives into themed trenches and tunnels.
Hulk, Manta, Kraken, and Mako, everything at Busch Gardens, and even Slinky are all examples of how to do an "unthemed" coaster that is still aesthetically pleasing and doesn't detract from the area it's in.
