Sure, they'd be an addition to the whole equation, but no more or less than anyone else. Yes, the "intelligentsia" are often integral in raising awareness of certain films, but they are also very often just an echo chamber. Just because a film is artistically well crafted doesn't make it a good movie, much less "culturally significant." The latter has very little to do with film experts, regardless of how well-respected.
Media and culture shape each other, but I would agree with that assessment.
The critics so often get it wrong, I think they'd do more harm than good. The RT fan and critic meters are often at severe odds with each other, and the fans seem to get it right more often than the critics. The Hobbit, for example.
Fair enough. I'm not married to the idea.
Maybe throw in the IMDB rating instead?
