I don't see how she spoiled Seussical. If ANYONE did harm to SEUSSICAL, it was AARON CARTER. Rosie O' Donnell can take second place on that. (Sorry, Rosie. Love ya, but you didn't act.)
As for funding her own projects, I agree with you there. I think its fine to fund tours, but to fund a Broadway production...five times within 10 years! A bit too much.
"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."
