A drama about bareknuckle fighting in the Traveller community has some crowd-pleasing moments, but there's not a lot to itThis feels like a fictionalisation of Ian Palmer's 2011 doc, Knuckle, about rival clans of itinerants holding bare-fisted donnybrooks in Irish laybys, but the tone is erratic. Writer-director Mark O'Connor aims for authenticity, tying the Travellers to those other migrant labourers persecuted by locals.
