It is much easier (and way more rewarding and beneficial to the ones doing it) to discuss, analyze, dissect and theorize upon, bad or average art works and artists, than it is to do so with good ones.
Poorly made art, leaves a lot of empty spaces around and inside it, thus leaving ample free room for interpretation. Good art on the other hand, does most of the talking internally, charging the space with questions and answers, creating a densely structured reality, which resist external interpretations making them redundant.
Nevertheless, it is a worthy challenge to engage with, making the rare ones able to discuss good work, precious allies.
Also, artists with an average talent, are the most ambitious. Always.
