After seeing TFA and TLJ in the theaters and left terribly unsatisfied, I voted with my wallet and refrained from seeing TROS , so it was satisfying to see the decline in box office from episodes 8 - 9.
I did the same thing after seeing Transformers 3 in the theaters. I realized I can't keep supporting these films, even though the tempting trailers always looked amazing.
All you can hope to do is to inspire improvement down the road.
