Few would dispute the supremacy of Cranford and Lark Rise to Candleford among the BBC’s current fleet of costume dramas. Measured, domestic and infinitely gentle, there are no Machiavellian footmen or illicit trysts here, just wholesome country adventures championing those unfashionable values of honesty, neighbourliness and hard work. The lamentable histrionics of the recent Upstairs Downstairs could have done well to note these successes, adapting material free from obvious drama (and in the case of Flora Thompson’s autobiographical trilogy, almost entirely without plot) and fashioning from it something credible and engaging. Lark Rise has its saccharine-sincere faults, but there’s no denying that with its characters back in the Sunday-night television slot, all somehow feels right with the world again.
