What are we without creativity? We'd have no culture. We'd just be robots. As art is subjective (though I'm not so sure about taste imo lol) I think whatever conjures something deep inside someone's psyche that effects them, even on, or especially on a subconscious level, it is art. It doesn't need to be strictly intellectual or emotional. A balance between both is perhaps the best kind. A multidimensional kind. I feel sorry for those who have no appreciation for abstract thinking because that's the most human part of us.
