Wrong. Hard SF is either based on current known Science, or on a convincing extrapolation of current Science. There is NOTHING in Elysium
which is not believable for the year 2154.
Allow me to note that 140 years is more time than passed between the Wright Brothers flight and today. More time than passed between Robert Goddard and the Space Shuttle. The shuttles in Elysium
had an unexplained power system, but certainly it was not an unbelievable extrapolation in a 140 year span of years.
I insist upon my definition rather than yours because by your definition, there have never been any true "Hard SF" movies, and 2001 A Space Odyssey
is a Fantasy - unless you can explain to me the Science of the Black Monoliths. I refuse to believe that time passes without technological advances, it's not credible.
Then there are matters of taste, where we understand that the movie maker departed from Science in order to make a better film. Such as the Cameron film The Abyss
, which happens to be a particular favorite of mine. Everybody knows the Science of breathing mixtures at ocean depths requires a Helium/Oxygen mixture - but I agree with Cameron in that having everybody quacking like ducks during the entire movie would have been too much reality, and would not have worked.
I questioned just one aspect of Elysium which did not meet with my knowledge of Science:
Warning: Spoiler! (Click to show)
I believe that the atmosphere on the Elysium space station either needs a physical roof over the inner surface, or a depth of 100 miles at one gravity to create one atmosphere of air pressure. Somebody promised me an explanation but it was not forthcoming.

Therefore I'm chalking up that one to "Bad Science", just as today, one can nitpick the Science in 2001 A Space Odyssey or in Destination Moon. Some people can master Physics as a school subject, but appear incapable of using it to explain the world around them. Whomever the Science adviser to Elysium was, he should have caught that one.
