The habitat in Elysium is quite bizarre. The entire donut is built Cabriolet style flying LEO and protagonists just lowers commandeered space helicopters through inner perimeter. It could be said the Chekhov's gun principle applied beautifully but quite bizarre.

Also there's a scene at the beginning where the main character looks up and it's just hanging up there, seemingly stationary. At LEO it should be zapping across the sky (the ISS orbits the Earth every 90 minutes).
