Art is subjective, and depends on the point of view of the subject it observes, his feelings and interests. But with things like the ones you show here, I would also ask myself: Is this art? I find neither expression nor quality in this, I don't like it. As for the photo that you say would be worth it, the one with the bathtub, I think would fit into what is known as "ready-made which is to intervene artistically objects that don't have an artistic function. I'm disappointed just like you, @gooddream. Happy Sunday, a hug for you.
