You know, it is possible to appreciate a piece of artwork without liking the show. And you don't /have/ to comment on every piece, especially if you don't know or like the show it comes from. If you don't care, that's cool, but don't comment saying how much you don't care. It makes the artist feel worthless and insults their work. You're basically saying "I can see you put work into this, but I'm not gonna talk about that. I'm going to talk about how much I don't care and you can't make me care, even if your piece of art is really beautiful, I refuse to talk about that aspect because I'm too focused on my own interests to bother." Can you honestly not see how you saying you don't care is more harmful than if you say nothing at all?
