As other said before me, this film is not for everybody. I'm not a critic, just an average guy who like s to watch movies sometimes but I must admit, this is one of my favorite film of all time.

This film shot mostly in a living room in front of the fire place while a group of college professors are having a conversation. A sci fi film without the special effects but depends solely on the stories and dialogue. It will draws your attention on the film not because of the visuals but it's thought provoking stories and ideas, the very foundation of science fiction. This film leaves me wondering and thinking in the end.
