I don't think art has to "say" anything. A great work of art can be highly communicative, evocative etc, or it can be nothing more than pure aesthetics, and anything in between. I consider everything I see on its own merits. I might just love looking at something, even if it has no other "levels" to it. That's good enough to be great art in my opinion. It can be a blurry, grainy print, or a technical photographic masterpiece, or an office building, or Guernica, or a carpet pattern. If it excites me, it's great. If it doesn't, I don't care what it says or doesn't say. That's all there is to it. Only my opinion, of course. Many would disagree. Picasso certainly would, as he differentiated between what he considered true art and decoration. I don't care.
