Day one and already felled by expectations. Les Enfants Terribles have brought some of my favourites to Edinburgh in past years: combining puppetry, shadow-play and intense sound and movement to create otherworldly characters. The Infant, while technically flawless and beautifully rendered, is less ambitious – a man, a woman, and a crazed interrogation about their four-year-old son’s drawing. The performances – particularly of interrogators Costigan and Samedi – are exquisitely paced, and the use of the minimalist door-framed set is perfection. But what is perfection without depth? This Godot-esque tease has toned down the tricks without notching up the character.
