After playing TV-movie victims for years, Farrah Fawcett is terrifically good (almost surprisingly so) cast as real-life child-killer Diane Downs, who tried to convince the police she and her kids were victims one night of a car-jacker with a gun. One is tempted to go on and on about Fawcett's multi-layered portrayal of a sociopath, yet this is a long movie--four hours with commercials--and Farrah has the burden of it resting on her performance (she carries it off with gusto). Ryan O'Neal is very strong, too, playing the lover who doesn't return her affections. A sad, violent story, but told with an intense, focused energy which makes it completely absorbing and ultimately moving. Farrah does Emmy-worthy work.
