As for how "lame-ass" (doesn't really make sense as for as ad hominem attacks go), I'm always open to the concept that I'm wrong. Want to explain why or are you just incapable of articulating a response that actually addresses any points?
If you're open to the concept, allow me to educate you, just becasue something is popular and makes money, doesn't mean it's necessarily, worthwhile, at all.
For example, those "magnetic health bands" that were all over TV a few months ago, people claimed that wearing these things would increase balance, help you lose weight, ect. People believed this and started saying that the claims were true, these products made money, but actually did nothing to do any of these things (several studies confirmed this).
Now, on the topic at hand, while some pieces of commercial "art" may be very successful , that does not make it necessarily good, or even art by definition.
If we judge something creative by how well it fares in the market, we've now put crap on a pedestal and said that it's the next big thing.
Consider this, if person A just scribble on a block of wood and try to sell it and it does well, that is considered very well done art, by your logic.
Now, if person B uses all their effort to make something worthwhile and fantastic, but makes no monetary gain or gets no fanbase, then it's not even worth your time.
So, have fun looking at overrated shit, because it's made money.
