And all art is subjective - I really don't see how anyone could think otherwise.

I disagree, although not by much.

There are objective observations to be made about art. There is craft and skill that can be measured and discussed. Films contain symbolism that can be hackneyed, cliche, obstuse, or elegant. Poetry contains meter and rhythm, and going with or breaking from them causes a specific effect. Some comicbook artists cant draw hands. Without these observations, all discussion on art becomes variations of "But that's just my opinion" repeated ad nauseum.

I agree mostly with your sentiment, that making blanket statements about art is very tricky given art's nature, but I would phrase it: Art cannot be all objective.
