CORONAVIRUS EDITION: In light of Coronavirus worries, it’s opportune to discuss BBC’s classic post-apocalyptic series, SURVIVORS (1975), in which Chinese scientists unleash an engineered virus, triggering a pandemic, and wiping out all but a remnant who remain to rebuild. This episode goes out in the spirit of facing such fears and scenarios from the safe distance of fiction and with wishes for the health and well-being of all who might listen.
