It's misery porn at its most prettily dishonest, but against all odds, Harrelson, Brie Larson and a gaggle of talented child stars render it soapishly watchable.

Larson is the weak link here as the adult Jeannette, a born-again neoliberal in an 80s power suit, failing to integrate her rich, boring boyfriend into her unconventional family.

Woody Harrelson gives a performance of borderline unwatchable hamminess in this really tiresome film, which sentimentally neutralises parental abuse into a supposedly fascinating angel/devil split.

The actors, including Ella Anderson as the young Jeannette, give it their all, but they look awkward and uncomfortable, particularly [Brie] Larsen as a tightly-wound Manhattan gossip columnist
