I saw NDDP in Vegas in 2000 and I have to say that, despite some major flaws in its structure and staging, I enjoyed it. The music was beautiful. Unfortunately the lyrics were dreadful.
I did not get to see it in London as it closed before I had a chance - so I do not know what, if anything, they changed in the show. The reviews in London were very negative but I remember thinking when I read them that, unless the show was greatly different to the one I saw in Vegas, it was not as awful as the critics painted it. Basically it needed a better book and new lyrics by someone who understands musical theater.
