this film is a variation of a theme we have all seen over and over again  the posiedan adventure in space. the characters are all stock characters  feisty heroine and judas and coward and etc. etc. the only question really is who next to snuff it. sometimes this tried and tested formula works  like in this case  but more often not  like the truly mind numbing red planet. so why does this one work. because it stylish. the acting is above average. and above all it isn not predictable. the conclusion isn not sign posted. i really had no idea how it would all end and was surprised at how it did end. that alone deserves top marks in my book. it an intriguing and entertaining movie. and though it was never likely to change the face of cinema as we know it and it doesn not disappoint.
