The Last Jedi is apparently the cultural enrichment film of the decade.
A better way to view the critic score is, "X% of film critics think this film is worth watching."
And the audience score is: "Y% of moviegoers who leave movie reviews on Rotten Tomatoes think this film is worth watching."
This is why Toy Story can get 99% (it's a crowd pleaser), and why daring, impactful films can sometimes get lower scores (they can be polarizing).
