Ahh, but then the show, having a two-week run in Fort Lauderdale, finds its magic. The first inkling comes with “Babkak, Omar, Aladdin, Kassim,” a comedic song in which the four down-on-their-luck pals try their hands at busking, singing and dancing in the marketplace of the mythical Middle Eastern city of Agraba. No, it doesn’t reinvent the stage musical, but it does tap into what — increasingly, as luck would have it — is “Aladdin’s” true treasure: It is an old-fashioned musical in the very, very best sense of the word, satisfying and spectacular.
