Actually, my gripe (from watching a fair chunk of this film) is that "The Marching Morons" was filmed, but completely butchered, and without credit. There are just far, far too many similarities here for it to be coincidence -- things which extend 'waaaay beyond the basic setup into specific situations, comments, reactions, and the like; and the entire thing flopped for me as a satire because it wasn't
sharp, it was itself about as subtle and witty as an elephant taking... well, I'll leave the rest of that simile unspoken, lest I manage to get myself an infraction.
Suffice to say that, whether admitted or not, this was Kornbluth's story, only bastardized to a hideous degree. That is what ticks me off: the lack of any genuine wit and, even more importantly, the complete disregard for crediting the original source -- which is itself a much-reprinted and well-known piece of classic science fiction! Idiocracy
may be about the dumbing down of society, but it strikes me that, in doing this latter, the makers of the film are not so much satirizing as capitalizing on that condition....
