"A bunch of different people appear, and they've got their own situations and reasons and excuses, and each one is pursuing his or her own brand of justice or happiness. As a result, nobody can do anything. Obviously. I mean, it's basically impossible for everybody's justice to prevail or everybody's happiness to triumph, so chaos takes over. And then what do you think happens? Simple - a god appears in the end and starts directing traffic. "You go over there, and you come here, and you get together with her, and you just sit still for a while." Like that. He's kind of a fixer, and in the end everything works out perfectly. They call this 'deus ex machina."
