An interesting but far too complex film, which although full of many good ideas, does not execute them well. The subject matter would best befit a short science fiction story, and indeed the content of the film is so slim that it quite noticeably outstays its welcome. Like most short stories, the film would have best been told from a first person point of view only. The film threads in the story of the operators, just not just the operated too, however. This causes the film to become distracted from the more interesting part of the tale, and as a result, it is at times quite bland. It is not that the viewer does not understand  there is just no reason to care. All that said and done, the film certainly has interesting elements, and it will keep one watching for at least three quarters of its duration. It is not really a poor film; it is above average, but I feel it could have been done a lot better.
