Evoking the middle-class relationship turmoil of much of Ingmar Bergman’s work, albeit without his propensity for dramatic heft, this Finnish film charts not so much a love triangle as a love rhombus. It is a mature piece stuffed with thorny relationship dilemmas, pre-occupied by sex and populated chiefly by a sparse cast of well-heeled, intelligent characters in safe, comfortable surroundings. If Bergman were alive, this is exactly what he would be creating.
