So, Elysium is about how the Rich People build an exclusive city above the world where they have amazingly great healthcare. The Poor People below have no healthcare and little girls are dying of cancer that some robot could heal in a second. So, a thieving Christ figure Matt Damon, who is also dying, must "sacrifice" his last days to break down the doors of an exclusive "heaven" and provide healthcare robots to heal the world.
Um, so we got blasphemy and socialist propaganda rolled into a sermon action flick. No thanks.
