Why does the second good guy get to win? Why do either of them deserve to win? The Force Awakens makes no clear point, but there should be a reason past “because they are the good guys,” and I have some ideas.
There’s a concept in character writing that when you create a solid character you should be able to know what they would do in any situation without thinking about it. Think of a character. They’re in a rush to meet someone very important. They knock on a door where this person is supposed to be and there’s no answer. What next? Do they knock again? Either of these outcomes offer meaningful insight on the character, but you wouldn’t have a brittle-boned character try to break the door down and then die at the doormat. I don’t think anyone would want to tell the story of a brittle-boned character who died to a door. Unless you were Supermassive Games, the creators of Until Dawn.
