As to Evans and "pure emotion": I'd say that's correct. For much of his career, he pretty much expressed that one pure, melancholic (I won't say maudlin) emotion, over and over again.
However, if you pluralize and say "emotions," then he doesn't cut it, as great as he is in many respects.
Sure, I'm oversimplifying, he wasn't always that way, but I believe there's also a lot of truth in what I write.
As for Gopnik, he's a very good writer and a very good journalist, but sometimes he gets out of his depth. Just yesterday I happened to stumble across a Gopnik article about wine, and since I sell the stuff for a living, I had many quibbles with the statements he made in his piece.
It's a recognized phenomenon that the closer you are to the subject of an article, the more problems you may find with it, whether for factual reasons, interpretational differences, or whatever. I recall a Gopnik article about Django that received a fair amount of flak on this board a while back.
I think Sangrey's on to something here.
