Right on, Wlady! I never cared much for Glengarry Glen Ross, the movie, even with the excellent performances by the actors, particularly Jack Lemmon and Al Pacino. Now I know why.
I followed your link to Simon's review, and thence to the Archives where I spent a delightful hour or so reading Simon's reviews. Then, for a comparison, I read a few reviews by Ada Calhoun, and in so doing discovered a fundamental truth about Simon's writing: he literally takes the reader into the theater. Calhoun, in contrast, brings to mind James Thurber's The Mail Animal. I refer to the protagonist's immortal line when the ex-campus-big-wheel raves about reading Reader's Digest: "Do you like bouillon cubes?"
Even Simon's swan song had class. I can only assume that New York magazine's reader base has declined in class, as has that of so many publications. Well, New York isn't the bastion of class that it once was.
