Brainstorm is a fascinating but frustrating film, simply because it dabbles in greatness but fails to develop the fullest implications of its provocative ideas. It's a visually dazzling film with outstanding special effects; directed by veteran effects creator Douglas Trumbull, of 2001 fame; but too caught up in marvels of hardware and software at the expense of its characters, who remain interesting but dramatically two-dimensional. The story involves the development of a headset recorder that can replay one person's experiences--even their emotional states--into the mind of another. The device obviously invites corporate or military exploitation, and Cliff Robertson plays a ruthless executive determined to tap into its lucrative potential. But when a scientist (Louise Fletcher) records her own death experience with the device, along with incriminating evidence, the technology's inventor (Christopher Walken) must unlock the mysteries of his colleague's suspicious demise and the very nature of death itself. Punctuated by remarkable sequences from the perspective of those who use the mind-expanding headset, Brainstorm dares to reach for ambitious themes and innovative movie experiences, and that alone makes it eminently worthwhile. But with a conclusion that too literally interprets the afterlife experience with conventional angelic imagery, and a disappointingly thin role for Natalie Wood (who died while the film was still in production), the film strives for profundity and settles instead for an inspirational light show. --Jeff Shannon

Research scientists Louise Fletcher ("One Flew Over the Cuckoo's Nest") and Christopher Walken ("The Deer Hunter") invent a machine that can record sensory experiences only to have devastating results when Fletcher records her own death.
