A lot of the problem was how to show Dusoleil actually passing through the walls. They had these strange flappy walls that looked silly from time to time. Malcolm Gets's glasses often fell off when he went through the walls.
Another problem was the translation from the French to the English. The lyrics were often silly, or inappropriate, and were not up to par with the music.
The musical also billed itself as a musical comedy, and while the show was quite funny in some parts, it was not a musical comedy like those that had recently opened (The Producers, or urinetown as examples). Many of the jokes were sex jokes, or equivalent to "potty humor." Some were funny, others were not.
The size of the theater was also a problem as even a smallish theater like the music box seemed to swallow up a small, dainty musical such as this one.
That being said, the music by Legrand was, for the most part, marvelous. Melissa Erico had some beautiful music to sing, and she sang it beautifuly. Malcolm Gets also had some fun things to sing. The supporting cast was wonderful..Norm Lewis had a wonderful song in "The Painter's Song."
It was most certainly a fun time at the theater. Some great moments, and some not so great moments. The court room scene was a great show-stopper, but the scene with the judge and his "sick ways" with the prostitutes was just odd. I still listen to the cast recording which recorded the show beautifully. The music and the actors were most certainly the best things going for the show, and the CD is a joy to listen to. Hope that helps a tiny bit.
