"Heart" is an engrossing study of extremes.This film takes us on an extremely profound journey of obsessions,manifested in four characters. Maria,the mother grieving over the loss of her son.Gary,the husband tormented by his wife's infidelity.Tess,the unfaithful wife & Alex,the lover. Each characters arch,is the fact that they are so human that it is easy to lose yourself in each characters personal journey.The plot itself is perfectly structered to allow the story to unfold itself. One of the best Brittish films I have seen in years.
