You should be neutral on it, Paul, because you haven't seen it. The reason the art label gives it a pass is because, as I said, I don't think any topic is exempt from artistic representation. Therefore, I think criticism of the movie isn't fair solely on the basis of its topic, therefore, I think it makes sense to remain neutral until you see it. Otherwise, you're saying, "You shouldn't make a movie about that! I don't care what your intent is!" Do you not see why I might have an issue with that?
"There are numerous reasons why one would object to someone's art.." Fine...except that you haven't seen the damn movie. That's a troublesome form of censorship. Granted, you say you aren't telling others how to feel about it...but you plainly feel that the movie shouldn't have been made, and you are expressing that. That's not far from censorship, emotion-wise, and that's not far from burning books you haven't actually read.
Extreme comparison, of course. And you're not really under attack here, you said, "I don't see why...," and I'm trying to explain my point of view. All in the spirit of discussion.
