Robert Hughes is the first name that comes to mind. I used to like his reviews in Time (when my husband "let" me read it; we only subscribed decades ago). He's also written some very good books: American Visions on American Art that I use as a textbook for that class. He's also written a recent book on Goya that I haven't read yet.
There are some blogs with some interesting writing about art; John Haber isn't bad. I'll have to keep my eye out and share other critics' names with you as they come to me.
This looks like something right up my literary alley.
I may just buy it for perusal on the capitalistic freeper cruise.
