Years and Years

9pm, BBC One

So good and so topical you never want it to stop, Russell T Davies’s prescient drama about the turbulent lives of the Lyons family marches on with an episode that sees the return of political campaigner sibling Edith, who raises fears (and hackles) in a TV interview saying: “The world keeps getting hotter and hotter and we don’t pause, we don’t think, we don’t learn; we just keep racing to the next disaster.” Elsewhere, the wheels threaten to fall off Stephen’s cosy existence and Viv Rook scents power.

Chernobyl
9pm, Sky Atlantic

This necessarily bleak and smothering drama about the 1986 nuclear catastrophe continues, placing star of the moment Jessie Buckley centre stage as Lyudmilla. With the dread dramatic irony that suffuses the whole piece, she is not minded to heed warnings about radioactive contamination. Jack Seale
