I propose

The Quiet Earth.

This film is a masterpiece of post-apocalyptica. Zac Hobson wakes up to find that he's quite literally the last man on Earth as everyone else seems to have completely vanished into thin-air. After a truly chilling first 10 minutes, the rest of the film is based around him (and us) trying to work out what the hell happened.

Eventually, Zac goes bonkers. Highlights of his madness include cross-dressing, roaming the city waving a shotgun, declaring himself 'Emperor of the World' and challenging God to a duel(!).

This is truly a movie that'll make you ask yourself "If I were the last man on Earth, what would I do?"

Societal Angst? = +1. It would spoil the film to explain why the world's gone to crap, but suffice to say it's down to white male scientists experimenting with technology they don't understand.
