For a mainstream example, take Fast X. It's an objectively stupid movie with a great audience score - because it's exactly what it says on the tin! Nobody is confused about what they're watching. Nobody thinks they're going to get terrific drama or romance or suspense. They're going to get the 9th sequel to a comedy action movie about dudes driving cars.
Blue Beetle: 78% critics, 92% audience
Gran Turismo: 63%, 98%
Elemental: 74%, 93%
Meg 2: 29% 73%
Haunted Mansion 38%, 84%
Indiana Jones: 69%, 88%
Little Mermaid 67%, 94%
Those audience scores are not "more accurate" in any way. People who are forced to see these movies like them less than people who chose to see it.
There also really isn't anything currently that fits into "the political correctness / marketing budget of the movie" claim of OP. It seems like they are just buying into cultural war nonsense. The closest I can find is Barbie and its critic score is 5% higher than the audience score, so not much of a gap.
