Director David Cronenberg handles his usual fondness for gore in muted style.

People like myself who find the character played by [Genevieve] Bujold (in one of her best performances) more interesting than either of the twins are bound to feel rather frustrated by the end.

An intense psychological drama which confronts [Cronenberg's] familiar preoccupations -- fear of physical and mental disintegration, mortality, the power struggle between the sexes -- without the paradoxical protection of visceral disgust.

David Cronenberg's study in psychological terror is, surprisingly, near-bloodless, and at once disturbing and fascinating.
