I don't know how anyone can call the score to BILLY ELLIOT "weak." Please explain. I think it's memorable, suitable, works, a great partnership with choreography, and just fine. I hardly find anything 'wrong' with it.
Is the show over-produced? I think certain aspects, like the central set piece, are not necessary, but I don't think they HARM the show.
"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
