Though it concerns a married lesbian couple with teenage children by the same anonymous sperm-donor father, The Kids Are All Right is a surprisingly universal comic drama that should strike a chord with many more conventional couples. Nic (Annette Bening), a doctor, is the practical, focused half of the pair, while Jules (Julianne Moore) is a more scatty, creative type, and their already volatile relationship is tested further when their son seeks out his birth father - easy-going restaurateur Paul (Mark Ruffalo). The kids take to Paul first, then, surprisingly, so do Nic and Jules, but when the latter embarks on a reckless affair with him, this unlikely love-in comes unstuck. The set-up is especially middle-class - Paul grows his own organic food, Jules is a landscape gardener - but some pitch-perfect performances really bring out the emotion of the situation. Best of all is Bening, capping even her performance in American Beauty, as a woman forced to face her partner's betrayal.

Two women, Nic and Jules, brought a son and daughter into the world through artificial insemination. When one of their children reaches age, both kids go behind their mothers' backs to meet with the donor. Life becomes so much more interesting when the father, two mothers and children start to become attached to each other.
