Ratings from professional critics are based almost exclusively on the skin color of the cast and the social messaging of the script. I can (usually) predict a 90+ Rotten Tomatoes score by looking at nothing more than the cast’s faces.

Public ratings from movie enthusiasts are slightly better. You tend to get fewer bitter, low talent journalism majors and aspiring New Yorker writers in the mix. They have less incentive to turn their review into a glorified virtue signal and instead just focus on the entertainment value of the movie.
