I understand that creative effort is a part of the artistic process, I'm just firmly of the belief that you need both. The only reason I didn't also say that drawing a realistic tree is not very good art is because it's not relevant to the op.
the first time someone did a black stripe on a white background it was probably quite cool but there's only so many times you can respect an abstract piece like that before u start thinking hang on
when I see paint everywhere and it represents that persons being I feel like maybe I see it and I'm thinking safe actually that's not bad
then I turn around and there's 5 or 10 more paintings doing the exact same thing and at that point there's no way I'm not thinking nah, that stops being impressive now
I don't think that doing someone elses idea but a bit different counts as enough creative effort to counteract the lack of execution level needed to complete it, and that to me is why pieces like that will never impress me, ever, regardless of how dumb that makes me according to rich people.
