I liked the staging with the set, too. And the extra involvement from the Narrator (bird mobile, anyone?).
But I did *not* like the dancing cow. It became a show about a dancing cow and distracted from the story. People couldn't wait to see what the cow would do next and not care about the characters.
"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."
--Aristotle
