That was very silly (as expected, given the source). One thing I didn't expect, and greatly enjoyed, was how "meta" the show is. Several songs comment on the show itself (e.g. "this is the song that goes like this", talking about standard tropes), and the watery tart's solo midway through the second act was hilarious. (No spoiler here, but if it comes up in comments, consider yourself warned.)
Providing the lyrics for the final song (hey, some people might not know all the words already) so the audience could sing along was a nice touch.
There are a few hooks for localization. Some cities scan better than others, but I assume touring companies are up for the challenge. :-)
