A friend of mine from a venerable entertainment-industry family once used a great piece of old-timey show-business jargon to describe a movie he didn't like. It was too center-door fancy, he said with a shrug. I'm not sure I know exactly what it means, but I can guess. In a theater, the center door is directly upstage from the audience. When a character enters from that door, it's an unambiguous declaration that the star has arrived. It's hard to come in through the center door in a natural, spontaneous way.
