I think I've mentioned that my favourite genre of film is Apocalypse. The Bomb, zombies (supernatural and viral), robots, AI super-computers, vampires, pandemic viruses, asteroids, comets, volcanoes, the sudden totally unexplained failure of all plant life (which is as close to an explanation as we got from The Most Depressing Book/Movie Ever Made Road), talking apes, pod-people aliens, tripod aliens, Triffids, long-forgotten buried dormant dragons, total economic collapse due to Evil Capitalists (too numerous to link), sudden ice ages triggered by industrial emissions reducing the salinity of the Gulf Stream (science!!), sudden unexplained plant-sentience (not making that one up, "They're mean, they're green and they're mad as hell..."), titanic reversals of the earth's polarity, titanic reversals of the earth's magma layer, overpopulation, underpopulation, and rampant Terry Gilliam... I love 'em all.
As long as it wipes out the stupid awful and pointlessly soul-crushing, artificial distraction-culture we've created since the 60s, kills off at least 80% of the population and sends the survivors back at least to the Middle Ages, I'm all for it.
