Despite a good premise about media and consumerism the film fails on too many counts to mention. While Finney is a fine actor he does not come off as believable at any point. He and the rest of the actors have to struggle with bad plotting and some horrid dialogue. It is not completely hopeless since there are some cool things but largely the movie is quite laughable and makes little sense.
As a thriller it falls pretty short, with some major leaps in logic and suffering from a horribly prolonged and repetitive finale. But what makes it compelling at its best moments are a number of intriguing concepts regarding the media and technology, also Albert Finney and Susan Dey are likable as the leads. An incredibly flawed film, but also one of Michael Crichton's most interesting works as a director.
