Richard Combs Sight & Sound Very uncomfortably directed: the performances are stilted and metallic (whatever is supposed to be assumed about robots taking over), and the perfunctory visuals leave the ramshackle plotdangerously over-exposed. Mar 19, 2020 Full Review Michael Sragow New Yorker Christie's passionate, vulnerable performance keeps pulling the entire movie into her point of view. Mar 27, 2017 Full Review Gary Arnold Washington Post What might have become an ingenious parable about the battle of the sexes ends up a dopey celebration of an obstetric abomination. Dec 21, 2015 Full Review Rene Jordan El Nuevo Herald (Miami) The film is so claustrophobic it's like spending a day talking between four walls. [Full review in Spanish] Aug 22, 2023 Full Review Steve Warren The Barb (Atlanta) Probably the silliest story idea of the year; and yet it's developed with a certain inner logic, infused with an excellent star performance and decorated with trippy visuals. May 9, 2023 Full Review Stephanie Monohan Screen Slate Donald Cammell’s techno-natal-horror film turns a domicile of the future into a claustrophobic chamber of female oppression.

Dave S Physically trapped in her home by an advanced computer system created by her husband (Fritz Weaver), Susan (Julie Christie) is ultimately raped and impregnated by the artificial intelligence. Sounds a bit outlandish? Well, it’s more than a bit outlandish. Sure, it’s prescient in the way it deals with the dangers of A.I. and technology. And sure, Julie Christie, as always, gives a great performance. The problem with The Demon Seed is the execution, ranging from Donald Cammell’s often ham-fisted direction to some brutal acting from many of the secondary characters to sporadic bouts of erratic editing to a bunch of highly implausible scenarios. Is it a bad movie? Probably not, but there are far too many problems with it to give it a solid recommendation.

Laughably cheap special effects, a ponderous script, and ugly production design combine with a stolid supporting performance by Fritz Weaver as the old-enough-to-be-her-grandfather bonkers scientist, married to a mousey looking Julie Christie, who is beautiful but sadly unable to act. Very boring, very forgettable. Rated 2 out of 5 stars 01/27/23 Full Review Audience Member Not bad enough to take down Julie Christy, but based on ending, where part two?
