This movie is truely a puppet show: If I remember correctly the camery doesn't move even once - just a dozen or so cuts, each depicting one scene with a different set-up, each scene remaining for several minutes. Persons move through the scenerey: sometimes you see someone doing something, sometimes you even recognize what he is doing. After a while you realize the same persons appear in different scenes. Even later you start picking up the story. Yes, there is a story, even though noone explains anything, hardly any word is said (was there a word at all? Maybe even not). all your concentration is needed to find out what is going on. The audience finds itself in the situation of an ethnographer meeting for the first time some unknown group of people, trying to find out something about them. The scenes, which initially seemed to keep on forever suddenly appear to change much too fast - you might be able to understand more, if they kept on longer.
Once you get into this movie, it is pure gold. If you want action, even one minute of The Puppetmaster will bore you to death.
