Dean R. Koontz's novel is adapted for the screen with this original and provocative science-fiction tale. An organic super computer dubbed Proteus has been created, but this entity has ambitions and thoughts that its creators couldn't have foreseen. The one emotion built into it is reason, and it doesn't want to just blindly follow orders; it questions things. For example, why it's so necessary to plunder the Earth's oceans in search of precious metals and destroy wildlife in the process. But what really intrigues Proteus (eerily voiced by an uncredited Robert Vaughn) is human life itself, and it traps Susan Harris (ever radiant Julie Christie) inside her own home, intending for her to bear its "child".
As one can see, "Demon Seed" is far from your typical sci-fi, and is positively creepy, and personal. For a while it's practically a two character drama, with the frightened Susan and the coldly determined Proteus locked in a battle of wills. With the high level of intimacy generated, it's easy to be with these characters and feel concerned for Susan's safety.
The popular subtext of this and similar features - "Colossus: The Forbin Project" and "The Terminator" - illustrating a potential for disaster in trusting our lives to machinery, is front and centre. The movie never insults the audience's intelligence, and as it plays out it's really fascinating to see. Even if one can take issue with the way the movie strongly dates itself - special effects, fashions, etc. - some of the visuals are still quite hypnotic and the scenario remains compelling the entire time, with a memorable and haunting wrap-up, which will leave the viewer to wonder about the "What next?" aspect.
The acting is strong from all concerned, with Christie an engaging lead, and the likable Fritz Weaver doing well as the confident human brain behind Proteus who realizes this creation of his can't be so easily controlled. It's also cool to have on hand the always entertaining Gerrit Graham ("Phantom of the Paradise", "Used Cars") as Susan's would-be rescuer, Walter Gabler.
Excellent widescreen cinematography by Bill Butler and chilling music by Jerry Fielding are also heavy assets in this solid shocker, one of the more noteworthy films of its type from its era.
Eight out of 10.
