You're telling me that the huge disparity between Audience and Critics reviews on RT isn't because the unenlightened masses are to stupid to realize what a cinematic masterpiece <insert preferred culture war movie> was?
In my experience the scores are not usually that far apart (< 20 points or so let's say).
In the instances that it is far apart, the differences are usually easy to articulate. Critics appreciate and notice technical aspects of films more than average viewers, and are quicker to recognize cliches and tropes.
This can lead to movies having much higher audience scores than critic scores, which flies in the face of the notion that critics are getting paid.
Well color me shocked, absolutely shocked.
