I post in the voice of Christopher Walken
I'll reply to some of the rest later, but this is a good example of the kind of problem I'm pointing to - "audiences" don't have anything to say, because they're made of individuals, who have things to say, but very few of them choose to say much - usually only ones with with extreme opinions re: the film's quality, unless you get someone out there to actually survey them. Anything which is self-selecting though will grab a very strange portion of the audience, not the audience as a whole.
I don't think this is true at all. I think audience members have a great deal to say. An important feature of water cooler talk is all about what people have to say to one another about movies and shows they are watching. Even pre-internet, the media would often try to capture and sum up what audiences thought. And I think it is possibly the most important reaction to consider. Art doesn't just exist for the art and the critics, it exists for the audience
But now we can get a much better sense of what audiences are thinking. It is pretty routine for websites like RT to have audience scores. But even without those, you can get a sense of peoples opinions by asking around, seeing what people are writing online, etc. Obviously more concrete data would be helpful, but this information is also out there. And we also can have some sense of what the audience thinks just by the fact that something was successful or a box office bomb.
