A lot of it is terrific and moving. I think not. This concern over media, or a return to traditional media, as a way of making sure art is art or art is good is regressive and paralyzing. If you want to paint, paint. If you want to blow bubbles, blow bubbles.
Individual artists make choices.
They lead or follow. Sometimes they lead badly and boringly. Sometimes they follow badly and boringly. I, for one, don't think Matthew Ritchie is exceptionally compelling or progressive, despite his obvious skill and ambition. He is certainly palatable and elegant.
