i believe the description is referring to dystopian movies, (it mentions two) not dystopian novels, even though novels are a much deeper resource.
dystopian movies, i feel, have a charm that is missing from most dystopian books, (does snow crash count?). most D novels are preachy and grossly inaccessable for those who dont immediately buy into the philosophy right off the bat. some of them just beat you over the head with hamfisted messages (does atlas shrugged count?)
D movies on the other hand, for the most part, are charming. most of them have specific villans instead of entire societies which makes them much more accessable. almost all of them are only semi believable probably due to the fact that they can really show entire ruined societies, at least the older ones. some of them are completely awesome. not that i am speaking out against books, i prefer reading. its just that some themes and styles work better on one medium rather than another. that being said, im in for one, and i would love to know where i can get my hands on that zombeer shirt
