Ever Since the World Ended (2001) on Netflix

Twelve years ago, a plague swept through, wiping out most of the population; in San Francisco, only 186 people remain. Two of them use jury-rigged batteries to power a camera and make a documentary. We see a variety of approaches to survival, from the artist and engineer who trade for their needs, to the surfers and woodsmen who fish and hunt, to the scavengers, and a communal farm. We also see how the community deals with those who threaten it, and how the youth are growing up with different values from those who knew our world.
