I know it's not the point of the article but I need to express my annoyance at the fact that Christopher Nolan is encouraging dvd/bluray purchase so much. He explicitly designs shitty sound in his films supposedly to make them sound better for the theater (i question his success in that effort) and then doesn't adjust it for the bluray. So even then at home you have to adjust the sound up and down to hear the dialogue while not getting your eardrums blasted out by the action sequences.

Ok rant over. Otherwise I agree wholeheartedly, don't trust streaming services to keep your movies for you. Bluray is the way.
