In terms of creativity and a superb theatrical experience, it's easily The Lion King, but
I absolutely adored Mary Poppins. It was amazing in London.
The ad thing about Beauty and the Beast, which I saw on tour and then on Broadway, is that it's become a theme park attraction. I don't think I'd want to see The Lion King, because I'm afraid that it would be the same, although perhaps Julie Taymore polices her shows and makes sure they stay fresh.
I have absolutely no interest in Aida (why, when Verdi wrote a perfectly good opera version), Tarzan or the upcoming Little Mermaid. I wish they'd put their Sleeping Beauty onstage. What a challenge: thorns, a witch that turns into a dragon, a dance with clothes carried by birds and squirrels, and that lovely Tchaikovsky score, not to mention a dress that changes from pink to blue and so on.
