That's fair. I'd say the only thing I find impressive about his work is the scale of some of it (assuming its actually being done surreptitiously). Besides that, the motifs are mostly unremarkable as far as wheatpasting/tagging goes. On the whole, he strikes me as the vanguard of turning street art into a sign of gentrification. When he first started getting recognized internationally he seemed like some kind of subversive spiderman figure but nowadays there's nothing gentrifying hipsters like more than a mural.

That said, tagging and wheatpasting is rad as hell and you all should try it if it's not too much of a risk. You don't need to be very artistically inclined to slap some glue and newsprint on a wall.
