I would agree. Rosenthal's basic position seems to be that critics at the time largely missed the mark on the hard bop period of the mid-50s to mid-60s, preferring instead to save their stars for music that was generally safer and more inline with "the tradition." There's a cultural aspect to the criticism as well, he says, where the largely black musicians felt their music was not being properly understood by the largely white critics.
But there are insightful critics and bad critics alike, certainly. It's of little use to paint the whole enterprise with a broad brush of dismissal.
Well, reading the Monk bio makes me think they sure missed the mark on him.
