Charlie Brooker opens his six-part series on television's relationship with fear by cutting between sketches and archive clips that show how often British TV has tried to scare its audience straight. Public information films aimed at children turn up looking almost sadistic in hindsight, warning about everything from electricity pylons to strangers with sweets, and grisly crime dramas get singled out for treating violence as entertainment while pretending to warn against it. Newsreader Michael Buerk appears in the archive footage Brooker mines for unintentional comedy, his gravity undercut by the absurdity of what he's reporting. Brooker narrates in his usual deadpan, pointing out the gap between the real risks people face and the manufactured terror television prefers to sell them. The mix of genuine unease and mockery is the point: he wants you laughing at the same footage that once, or still, unsettles you.
