Someone said :
He hasn't progressed or grown. That's my point. He makes mildly creative pieces that get a small chuckle and not much else.
Good artists are always pushing themselves. Banksy has coasted from day one.
Perhaps it's us that hasn't progressed or grown. Why should an artist progress when some of the basic things we can learn from their work, needs to be learned over and over again?
I think the point of the "pun" based names of his stuff is a comment on what it takes now a days for people to be interested in something.
Good artist aren't necessarily the ones that progress and push themselves for the sake of progressing, they're the one that don't care what people think as a consumers of art.
