Ginsberg, at least, was an enormously great poet.
I believe it was Alexander King who said something to the effect of, “Talent is a strange bird. It’s known to perch in the most unlikely trees.” Ginsberg was one such. Great, great talent. Angelou - mediocre, at best.
I never saw it although Ginsberg was always pushed on us, but I’m one of those who can’t judge poetry anyway, like a man with no taste buds trying to know what you are talking about with preferred foods and flavors, aside from Tennyson, I have never understood why they don’t just write it out.
