The parts of the movie that are going to resonate the most have the pacing they need to bring up one’s own memories of listening to a grandparent’s advice, of doing something you shouldn’t have to impress someone, or working up the nerve to talk to someone you liked. Perhaps these resurfaced memories are an unintended souvenir of visiting Branagh’s “Belfast,” but it’s one that may stick with moviegoers for quite some time after the credits roll.

The film feels true in the way it must be exploring Branagh’s memories of a tumultuous and confusing time, and the way it pays tribute to a vibrant community as that community is irrevocably changed.

Branagh’s most personal film is imperfect, but the emotion that it builds in the final section, as the family plays out a wrenching universal drama of emigration, is searing.

The affectionate cine-memoir is rendered all the more effective on account of young discovery Jude Hill and its portrayal of a close-knit family (Ciarán Hinds and Judi Dench and stay-put grandparents) crowded under one roof.

The result is engaging, tender film-making which tugs at the heart-strings, spurred by a sympathetic cast and the young lead, newcomer Jude Hill.
