The revolving door of films coming to and leaving Netflix can be a real pain. I've often had a cool movie pop up in my recommended list, but when I finally settle down to watch it, I find that it's already left the service. Fortunately, the upside is that when a beloved but maybe slightly forgotten film appears on the platform, it gets another moment in the spotlight. And today, it's the turn of one of the best science fiction movies of the 21st Century: Neill Blomkamp's District 9.
