I just got around to seeing a few Post-Apocalypse movies I've been umming and ahing over buying for a while, Future World and Scorched Earth.
Scorched Earth was a pleasant surprise, too obvious in it's western influences perhaps, but after watching the steaming pile that was Future World it seemed like a bloody masterpiece.
Scorched earth is well worth a watch, even if you could basically switch out the setting for the old west without anyone noticing.
Future World was sadly a complete mess.
