Thanks to Unk's review, I found out Iron Sky was available for home viewing and watched it on the Roku tonight. --Not quite the film I was expecting but in many ways better. Oh, it's a bit of a B movie and most -- maybe all -- of the characters are preposterous caricatures, but it's a (dark) comedy, after all. (It ends on a very dark note, but by then you're looking at the entire human race in half-shocked, half-amused laughter anyway.) As science fiction movies go, it's pretty good -- plenty of well-assorted widgetry, almost no stopping to explain any of it; the players take it for granted, just as they should.
There are a number of call-outs to other films, one of which was laugh-out-loud funny.
If you don't mind the U.S. government being as much the butt of the joke as the bad guys are, it's an enjoyable movie. Unk called it "so bad it's good," and it is right over the top, with impossibly compressed time scales and violations of orbital physics galore; but for all of that, more pretentious SF films could learn a thing or two from Iron Sky and I hope they do.
Somebody'd better be optioning Heinlein and C. J. Cherryh. These days, film industry has the technology to do those stories right. I sure wish they would.
