Whoopi was great. She had class. At least in the two ceremonies I saw her host.
Crystal is the best. He is cool, smooth, classy, and hilarious. Respected.
Steve Martin, in his last hosting ceremony, was held-back some. Funny, just not appealing.
Chris Rock is funny, and I'll even say he is hilarious. And I am sure he will get a lot of laughs and recognition.
But his attitude/body language, and sense of humor, I believe, is inappropriate.
"The Spectacle has, indeed, an emotional attraction of its own, but, of all the parts, it is the least artistic, and connected least with the art of poetry. For the power of Tragedy, we may be sure, is felt even apart from representation and actors. Besides, the production of spectacular effects depends more on the art of the stage machinist than on that of the poet."
