What. There is a problem in art with most people misunderstanding it. As someone earlier in the thread mentioned, art is about creative expression - there is no aspect of comparison in terms of what artform is better, although one might compare how well a work fares in conveying that message with another similar work. But subjective? How well something accomplishes it's aim isn't subjective - if you mean enjoyment of particular works of art is subjective, then yes, but subjective in achieving it's goal? I'd say no.
