Sunday 9pm Channel 4
The anatomy of a Dunblane/Hungerford-style 'shooting spree' – this stunning new drama is from the writer Tony Grisoni (Red Riding) and the director Sean Durkin (Martha Marcy May Marlene), who makes his British television debut with the four-part drama. A top-notch cast ranges from Sean Harris and Shirley Henderson to Eddie Marsan and Rory Kinnear, the last-named as a cynical television journalist originally from the town. Grisoni says that Southcliffe is primarily a study in grief, but it's also a visceral why-dunit that draws you into the fictional Kent coastal community in the process of been blown apart by a lone gunman, just as the non-linear storytelling cleverly binds you to the fate of the characters. A must-see.
