I found some other screen-to-stage ventures much better. There have been others that were critically-acclaimed (THOROUGHLY MODERN MILLIE, THE LION KING, GREY GARDENS), so I'll compare to other non-favorable adaptations.
9 TO 5 was not as good as THE WEDDING SINGER, XANADU, and I cannot believe I am saying this, but not even LEGALLY BLONDE. 9 to 5 was better than HIGH FIDELITY and, from what a friend says since I didn't see it, CRY-BABY.
"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
