This is based on a much-loved poem in Swedish written in 1956 (when my school debating club seriously considered "That man will never reach the moon"). Bear that in mind and much makes sense - more sense than the poem ever did to me when I first tried to read it. Much that purports to be science is just poetry. The film-makers have made some attempt to update the plot and the setting, bearing in mind that we have all seen 2001: a Space Odyssey..
The science is still cheesy. The ship has lost all its fuel, but power is uninterrupted and water is abundant (there is not only an extended lesbian shower scene, but a 20m swimming pool!). The architecture of the ship is absurdly angular, but nothing ever springs a leak. The ship's interior has been compared to a shopping mall and a cruise ship, but manufactured goods never show any sign of running out, and the whole thing seems absurdly understaffed.
It's basically an exploration of how an isolated group of people copes when it is cut off from Earth, its memories and hope. The main characters are sufficiently well drawn to explore these themes in, for me, a satisfying way. On those terms, it does well and is worth watching, though you must fill the hints in the chapter headings with your own deductions.
