Translation: worship and adoration aren't useful critical positions. No kidding. The point is that Kael is here belittling critical appreciation of directors, written in detailed and thoughtful pieces though it may have been, not as useful criticism but as worship and adoration.
This worship of the director is cyclical—Welles or Fellini is probably adored no more than von Stroheim or von Sternberg or De Mille was in his heyday—but such worship generally doesn’t help in sorting out what went into the making of good pictures and bad pictures. (1971)
