That works fine when it comes to television shows, because television ratings are not precise; they are more like a scientific poll. The money producers get for TV shows is upfront, and your viewership, regardless of whether you like it or you don't, is not counted if you are not a "Nielsen family."
On the other hand, when it comes to motion pictures shown in a theater, the only way you can "judge" it is after you have already put your hard-earned dollars in the coffers of the filmmakers, and if you are indeed offended by the product, guess what? You're not getting that money back. It's theirs now. Your adverse judgment doesn't mean jack squat to them, because you've already paid them to give your opinion.
For example: I am not going to see the new movie Saved!, the satire that supposedly is "sweetly subversive" in targeting Christian youth. The filmmaker, a former parochial school student, goes to great pains to insist the movie doesn't "bash" Christians, but from everything I have seen and read of the movie, I believe it presents a caricatured subculture of comically stupid anti-Semitic gay-hating judgmental "Christians" (the 'bad' ones) and contrasts them with sweet, cool, Christians who are accepting of Jews (as if that was unusual), teen pregnancy and homosexuality. (the 'good' ones).
Now, I can only guess at what the movie looks like as a whole, but the critics and the filmmakers (including R.E.M's Michael Stipe, who co-wrote "Losing My Religion") all say, "See it, and judge for yourself," fully knowing that if I do see it, and verify my suspicions, I will have had to have paid them to do it, thus coaxing money out of me that they wouldn't have gotten if I had just trusted my instincts and ignored the movie.
Sorry, I am not going to be suckered into that.
I'd rather retain my ability to think for myself, instead of only knowing people tell me about it. Moore can have my $5.
I think of it as creating jobs. :)
