I was pleasantly surprised by this film. Too many of these outer space adventures are clones of each other with exploding effects, fast than light travel and so on. This film is a bit more cerebral than that and has a well written, well-executed story. It was intriguing and actually quite frightening as the events unfolded. Jane Perry was excellent in the lead, and, Noeleen Comiskey, the first astronaut to travel into space in her altered body gave a compelling performance.
