Nightmarishness meets nostalgia as Jamie Dornan and Judi Dench star in a scintillating Troubles-era coming-of-age tale

There is a terrific warmth and tenderness to Kenneth Branagh’s elegiac, autobiographical movie about the Belfast of his childhood: spryly written, beautifully acted and shot in a lustrous monochrome, with set pieces, madeleines and epiphanies that feel like a more emollient version of Terence Davies. Some may feel that the film is sentimental or that it does not sufficiently conform to the template of political anger and despair considered appropriate for dramas about Northern Ireland and the Troubles. And yes, there is certainly a spoonful of sugar (or two) in the mix, with some mandatory Van Morrison on the soundtrack. There’s a key climactic scene about how you disarm a gunman in the middle of a riot if you have no gun yourself, which has to be charitably indulged.

But this film has such emotional generosity and wit and it tackles a dilemma of the times not often understood: when, and if, to pack up and leave Belfast? Is it an understandable matter of survival or an abandonment of your beloved home town to the extremists? (Full disclosure: my own dad left Belfast for England, though well before the era of this film.)
