Query: Gravely disappointing

I just didn't buy the premise of this movie, painting Hilary as long-suffering and Jackie as capricious. There was very little indication of what made her the great musician that she was. The whole family was a little sick, but I think Hilary was the really certifiable one. I have always loved Emily Watson, but this performance was not among her best. The mimed cello playing was unconvincing. The fox-like Rachel Griffiths had some moving scenes, but this seemed like a self-serving attempt of an ordinary soul to "set the record straight" about her brilliant sister. The movie also suffered from inept concert sequences and the usual misguided cinematic attempts to portray the life of classical musicians. The whole thing left a profoundly sour taste in my mouth. Why not look at a video of Du Pre performing to cleanse the palate?
