If you haven't watched in years you should, it's a smart distopian fantasy and old enough that a remake might have some interesting ground to tread. Hell it can't be worse then the last 3 star wars flicks, can it?
Oh, they are certainly saying something. SciFi is a vehicle for social engineering. StarTrek (tng and later), for example, are constantly preaching; it is so annoying. Others impart existential angst (e.g. the civilization of The Alien). And nearly all -- even the supposedly utopian visions such as StarTrek's -- insist that the future of mankind is a Intergalactic-Military-Junta and one must wear a color-coded uniform.. I want to see someone actually do justice to Frank Herbert's Dune. (I am not holding my breath; that book is clearly subversive in context of contemporary (geo-)political realities).
