I have a feeling that this would be destined to be one of those abandoned amusement parks, much like Boblo Island from my home town of Detroit or Autoworld from nearby Flint. There might be a short spike of interest after the movie, but after that, Supe’s rep was in the wringer as the “Big Blue Boy Scout” (and the sad, mulleted attempts to try to ditch that epithet) made him not quite popular in the following years.
However, that Neal Adams sketch? Holy crap, that is super fantastic! I love everything about it. It’s got a lovely retro look that was probably out of style by the time the 1970?s rolled around, but man does it ever scream Space Age in the best way possible!
