I heard of this first when checking out trashy VHS tapes which where being sold very cheaply when DVDs first came into vogue, it was titled the same as the book but apparently was also issued under the title "Summer Camp Nightmare" (seriously there's so many eighties movies dedicated to making people shit themselves about camp that I'm surprised it didnt disappear altogether).
However, this one sounds smart, or at least the book which inspired it does, why do you figure its sort of been forgotten? Is it just because its considered a poorer version of Lord of The Flies, that theme having been done? Not many people remember WE but they do remember 1984 for instance.
Or is it that the protagonist, while opposing a revolutionary authority appears to be or is portrayed as communist in his sympathies? I know the socialistic ideas or messages have been down played to disappearence from both 1984 and Animal Farm, both being books about (and this shocks the shit out of libertarians) the betrayal of socialism rather than anti-socialist books per se.
