After 15 years on the small and big screen, Julian Fellowes' hugely successful period drama sees Downton Abbey close its doors for the last time - and it's a fitting, hugely entertaining finale.
The opening shot sets things up nicely. We're in Picaddily Circus in 1930 and the camera goes inside a West End theatre (which will later become the Noël Coward Theatre), where Bitter Sweet, a Noël Coward play, is on.
Among the audience are various inhabitants of Downton Abbey, from both upstairs and down.
Times are changing. The class divide is still there, but its dividing lines are valleys rather than mountains.
Plot-wise, there's a lot going on. Hugh Bonneville's Lord Grantham is finally going to hand the Downton Abbey keys over to his daughter, Mary (Michelle Dockery).
But Mary finds herself in the middle of a scandal that shocks posh circles when it's revealed that she's now a divorcee - something greatly frowned upoon in those days.
She finds herself shunned by most of her peers, while an invasive press chase her to titillate their readers.
Meanwhile, her sister Edith (Laura Carmichael) and husband Lord Hexham (Harry Hadden-Paton) come down from their home up north to support Mary.
Also at the Abbey is Paul Giamatti's Harold Levinson, Cora's brother from New York. He's accompanied by his financial advisor, Gus Sambrook (Alessandro Nivola), who promptly makes a move for the vulnerable Mary.
Downstairs there's much change with Daisy Parker (Sophie McShera) set to take over the running of the kitchen, while Anna Bates (Joanne Froggatt) is expecting a new baby.
Daisy also joins Carson (Jim Carter) as new members of the County Fair board - which raises a few hackles for being 'the wrong kind of people'.
As for the guest stars, Arty Froushan is particulary memorable as a young Noël Coward. He turns up at the increasingly crowded Downton Abbey in the company of Dominic West's Guy Dexter, to entertain all by being very Noël Coward.
All told, it's great fun and belts along. But it's over far too quickly - we may never see its like again.
