Critic and audience scores are more and less important depending on the movie.
Do you want to find movies that are well done, break new ground, or include the tropes that critics love? Critic reviews are helpful.
Do you want something that is well done in a genre that critics tend to look down on, like horror or comedy? Audience reviews are helpful.
But any kind of score aggregation of either group is far less useful than reading a review that clarifies whether the movie includes things you like a lnd whether they are well done. A horror movie that has reviews that mention frequent jump scares will drive me away because I don’t like them that much unless they are frequent and well done. Someone else might want to see it because that is what they enjoy!
Some critics also focus more on whether the movie is trying something new rather than doing what it is trying to do well.
It isn’t like they mark a drama down for doing stereotypical drama stuff over and over and over again like they do with comedies or horror. Comedies and horror tend to suffer from people not all finding the same stuff funny or horrifying, while anyone can say drama is drama even if it is melodramatic with manufactured drama.
