There was a moment where Han asked Rey to join his crew, and I thought that was a good scene between them, but it got squashed by her refusal. It would have been so much more effective if her character had wanted to get off Jakku, and a backstory of her loneliness had been played up leading to that moment, and then she accepted Han’s offer. That would have created a far more significant bond between the two of them.
And, if she had wanted to get off Jakku, the complaints would have been that it’s just copying Luke’s story.
The thing with Rey’s story is that she DIDN’T want to leave Jakku. She was ever hopeful that her family would come back to collect her. This was the hope that kept her going. As soon as she was off the planet she needed to go back. She was terrified that they would return and she wouldn’t be there. When Han asked her, you could see she really wanted to join him, but knew that she couldn’t . The hope that they would return wouldn’t let her. It wasn’t until after the force vision and the conversation with Maz, that she came to the realisation that they were never coming back for her.
One thing we should remember when discussing character arcs and the like is that, unlike ANH, TFA designed as a standalone movie. It’s part of an intended trilogy. Character arcs will be completed over three films. That’s just the way that big blockbusters work these days - they are written as 6 hour films split into 3 parts, rather than 3 self-contained (but sequential) 2 hour films.
