I love the internet, most of the time.
Like when it can supply me with not just the name of a half-remembered tv-miniseries, but the entirety of it. Mark Harmon has had a long career, even if I don’t realize it sometimes.
The film is just as over-the-top-silly as I remembered it. Caricature villains, a rigid social structure under autocratic rule offered up as a impossible utopia to the messiness of a real world under democracy, doomed by the frailties of human ego.
And yet, it still manages to age remarkable well. It helps that 90% of their time is spent on a liner built during WW2.
Most annoying plot hole is the whole “it’ll never work” rigmarole over the heat exchanger. What exactly did the script writer think the difference was between a heat exchanger based on lava, and a scotch boiler based on oil? Pointing out that simply generating more oxygen doesn’t remove carbon-dioxide would have been more believable. Whatever.
turns out to be better than expected. Ends on a much more sentimental and thoughtful note than I would have thought possible from such a silly premise. Good performances and lots of 80′s fashion disaster flashbacks, with of course a 
reference…at least one that I caught, surely there were more =p
