What makes art or media “good” is a collective agreement on what “good” is. What standards we all agree upon. This means that if you say it’s shit thats you opinion, ita not an objective fact. Its subjective. What is it they say? beauty is in the eye of the beholder. One mans trash is another mans treasure.
That doesn’t make a lot of sense. You claim that it’s about “collective agreement” and each person’s individual opinion at the same time. Those are two different things. If it’s about personal opinion than collective agreement doesn’t matter. If it’s about collective agreement than my individual opinion doesn’t matter. Which one is it?
And I just gave you different meanings of ‘being in a bubble’. You’re simply using it wrong. But the fact that you refuse to accept that doesn’t mean that you’re in a bubble because it’s not what it means.
And yes, what is or isn’t good art or even what is or isn’t art over all is a matter of personal philosophy. You could argue that anything man made is art. You could say that every mass produced plastic toilet plunger is a work of art as long as one person in the world finds it beautiful. And my only argument against it would be my personal philosophy that there’s more to art than opinion of few individuals and that art and especially good art needs to fulfill higher standards than that. In my opinion you can objectively tell how creative, original and well executed a work of art is and by that you can judge how good it is.
