As an aside, that's how I feel about this trilogy. I saw the hero story with Luke and the struggle against the dark side and the Empire and I don't need to see it again. I agree. What's the point of doing the same story again? But I digress...No, not really. I've seen that with Luke. Don't really need to see it again.
But I'm sure you'll agree a character needs adversity to grow. What is Rey's adversity? If she doesn't struggle with anything, how can she grow? How can she develop as a protagonist?
