I liked the park, Superman is really top notch. I actually really liked Rattler too, well at least the first and last parts of it. The middle section is pretty lack-luster. Poltergeist needs the Outer Limits lap bars, BAD!!
All in all, it is a good park, and I think the attached waterpark is free with general admission. I didn't go there, however.
