Throughout the film, one can`t help but side with the precocious Breslin, which I`m not sure was the filmmaker `s intention, as her mother, as played by Cameron Diaz, comes as a hysterical bitch. Cassavetes is so bent on portraying Diaz as Kate`s tireless caretaker, that he doesn`t even have Diaz acknowledge her other two children in the film. Heck, Diaz only has two dialog scenes with Breslin, one of which ends in a slap, the other taking the form of a courtroom cross examination. It would have been nice if at least one scene had been included where it seems Diaz has any concern for her other children, but rather the whole film focuses on providing Diaz with teary, Oscar-bait sequences with the saintly Kate.
Probably the only good thing I can say about MY SISTER`S KEEPER, is that some of the supporting performances, particularly from Baldwin, Patric and young Breslin, are quite good. They make the film worth watching- at least until the shamelessly manipulative climax- which supposedly is a major departure from the thought provoking ending of Picoult`s book.
