The Retreat, Park Theatre, London, review: Sam Bain's bleak comedy drama smart bombs spirituality-lite

• In a Buddhist retreat, in the hills of Scotland, former city boy Luke is drying out, and trying to find oneness through meditation and guidance from the retreat's owner Tara. Luke’s spiritual quest, a month away from completion, is interrupted by the arrival of older brother Tony, who brings bad news, and certainly uncosmic vibes. Sam Bain’s The Retreat piece does not lampoon Buddhism, but more the hollow kind of 'spirituality' that is just another obsession for people who treat a search for inner peace as a kind of competition.
