I'm just the opposite I don't believe Rey had any arc in the movie but at least Finn had one, albeit a sudden and weak one. He's a loser who was barely a functioning Stormtrooper and wanted nothing but to leave all that crap behind but decide in the end to help and become a hero. The Han Solo arc if you will.
What's worse for Rey is that the film is hell bent on capturing some classic SW imagery while with her character, especially on Jakku, but doesn't understand how those images run directly against her character. For instance:
Let's look at this classic image from ANH:
I don't think I need to tell you what this image is supposed to make the audience feel, it encompasses Luke's internal struggle with wanting nothing more than to leave his backwater home and his familial obligations. All he wants to do is leave home and experience some adventures but he feels trapped on Tattooine.
Now, let's look at a similar scene in TFA:
So, in this scene a few things happen and Rey does a few things that later make no sense as we learn a few things about her character. You see we're told by her that she is waiting for someone on Jakku, in fact that's all she can talk about and all she wants is to get back there in the film to keep waiting. However, that entire sequence portrays the exact opposite and instead invokes feelings similar to Luke of a character who wants nothing more than to leave Jakku. We see her put on a classic Rebel Fighter helmet as if she wishes to secretly join the Resistance and get mixed up in space adventures (you know like Luke) and the camera focus on her as she watches a ship transport leave. Again, such an image invokes the idea that she would want nothing more than to leave the planet, however, we know now that she wants to do just the opposite.
Thus, wouldn't it make more sense in that scene if she was intently watching a starship arrive on Jakku, hopelessly believing that
this is the ship the person or people she is waiting for have returned? You know that classic feeling as a kid when you were waiting for someone to arrive and thus every car was
that car or no, no, its definitely
this car driving slowly.
