The more I think about it, the more I like this movie. It has stayed on my mind for quite a while. I think I'll go see it again
I think this is one of the few (if any) scifi movies I've ever seen in which the basic plot and theme of the movie had virtually nothing to do with science or fiction. The scifi aspect of this film is completely secondary to the main point of the film, which may be why it carries such an atmosphere of reality.
Unfortunately for me, the scifi parts it's missing are most of what I enjoy about scifi, so this is a very hard film for me to rate. A very unusual combination of story/film elements.
I would be interested to know what others think.
