I know my own movie-watching behavior changed a lot of with RT. I'd avoid any movie that had less than a certain score and gravitate to the ones that had a higher score.

I can see how a movie having a shitty RT score could be impactful to the film makers.

I don't use RT so much anymore (avoid a lot of reviews, honestly) because it killed the fun for me. I'd rather discover my love for a movie than have my expectations set up front.
