I watched this last night. It was a deliberate homage to sci-fi "trippy" movies of the 70's, with the most obvious nods going to Kubrick's "2001", Lucas' "THX-1138", and just about anything by David Cronenberg and David Lynch. Set in the futuristic year of 1983, it involved an evil doctor who had undergone mind-expanding drug therapy in 1966 and who now has a prison-like sanatorium/lab, where he clashes with a psychic young woman while trying to maintain his own grip on reality.
The acting could be stiff and unintentionally humorous at times but that was part of the charm. It was very slowly paced at times (particularly during dialog scenes) and felt "heavy" (this is not a light-hearted movie by any stretch) but I liked it because it captured that whole retro feel just about perfectly, using period synthesizers heavily throughout, and was filmed in technicolor using Panavision lenses. It really did feel like a lost movie from the era, and there is something strangely reassuring about that in this modern era of overly-CGI'd, overly-actioned movies. However, aside from great visuals and sound, those looking for a strong story or a clearly-explained concept are going to be disappointed.
