This very well written movie review over at Slate is a month old, but I just came across it today. Idiocracy is the latest from Beavis and Butthead and Office Space creator, Mike Judge. The premise is interesting: the selfishness of Suburbanites leads them to create fewer and fewer children and they are gradually out-produced by those of lesser intellects. An experiment causes an average Joe (a GI Joe, at that) to be cryogenically frozen and to wake up in the year 2505. He finds a very stupid America when he awakens. Read the review to get a better sense of it.
Apparently the movie is not getting much play or making much money--but it sounds interesting to me. Perhaps it will do better when it comes out on DVD.
