I love British drama, and I think it has to do with the British culture where no matter how damaged or depressed a person is, they are always trying to be pleasant and make others feel comfortable...and that is very pitiful for broken people.  This movie left me emotionally drained, and it is absolutely brilliant, with perfect performances all around.  Timothy Spall and Brenda Blethyn shine as a brother and sister whose lives are just in turmoil...and the appearance of an illegitamate black daughter makes it get even more chaotic.  I was mesmerized by the acting in this film...and even though it is very high concept with so many characters with such emotional baggage, it felt 100% realistic.  Simply "bloody" wonderful.
