The film comes alive in the last third with a good, provocative, conceptual question about society and individual human worth. But the sci-fi component is not required or even germane to that question. Further, the sci-fi feature is poorly developed, lacking the complexity and richness which could have accompanied the particular fictional mechanism. The majority of the film takes the viewer in a shallow and different direction from the point which becomes apparent near the end. Watch it to appreciate what might have been.
