John Cassavetes’ Love Streams shapes up as one of the filmmaker’s best, both artistically and commercially, in some time, emotionally potent, technically assured and often brilliantly insightful.Reflecting the title, the plot begins with two separate flows. Robert Harmon (Cassavetes) is a successful writer from the Gay Talese school currently researching the subject of love for sale on a first-hand basis. Inter-cut is Sarah Lawson’s (Gena Rowlands) story – an emotionally erratic woman proceeding through a divorce and custody case. One can nit-pick about the picture’s length and use of repetition but these are minor points in the overall strength of the production. The dramatic rollercoaster ride of frightening and funny moments leave little room for indifference.
