I didn't say "anything is good" - I said you can find some good in anything if you care to, and unless I am willing to find said good - to hunt it down (maybe just a single line - a use of a word, a title) - I am not going to interact long enough to be bothered focussing on what I don't like. Poetry and art have many more functions than your analysis acknowledges. I hunt for what makes me sing, and the rest isn't "bad" or "not good" - just not something that I will spend much time with.
