Thinking of Robbe-Grillet, I'm reminded of Simon Schama's great PBS TV series last year about artistic masterpieces. He wonderfully highlighted works by geniuses like Caravaggio. Then he did an episode on a 20th century American abstract painter-- I can't recall his name. Rothko? Schama went through his usual effusive explanation, then the camera panned and you were looking at a big blob of paint.
It's the same thing with Robbe-Grillet. The critical establishment can gush and point, but when you look at the actual work there's not a lot there. You're looking, basically, at a blob of paint.
Or as Oscar Madison said, "It's not linguine, it's garbage."
