Once you get past the first 20 minutes, which contains the worst of the acting and the expository dialogue that invariably that starts with "As you know, Mars/the spaceship/our oxygen supply...," this is an enjoyable and intelligent movie. Actually, with the proviso that this is indeed science fiction with regard to the more fantastic elements, they made a better fist of the science and technology than any of the Hollywood blockbusters about Mars. The production values are surprisingly high, although real space nerds will notice that the interior of the mars landing spaceship bears more than a passing resemblance to a shuttle mock up and Blake's 7 fans will notice the wandering-down-the-same-corridor-with-different-lighting trick.
