Overall, I'd say 5e art has bought into the contemporary Cult of Omnicompetence: everyone is always great at whatever they do and ultimately decent-hearted. 
Where are the screw-ups who manage still to be good at something the party needs? Where are the scoundrels that don't secretly have a heart of gold? And why is everyone so insufferably self-assured? This 
is one of the points 
Stefano Rinaldelli made just before opening this thread, and yes, he 
did get unfairly dogpiled for it, as did 
beancounter. I don't think they deserved such treatment for the sin of questioning a prevailing orthodoxy. People who relish cultural critiques shouldn't be so fragile when the tables turn and their favored sub-culture starts to receive one: it's a simple matter of the goose and the gander.
With all that said, though, it's still the case that the new art doesn't really bother me; it merely isn't the art 
I would use, and that's hardly a big deal.
