The Broadway season has many openings left before the late-April cutoff, but it seems safe to say that none is likely to be weirder than 'Amelie.' Given the bushels of imagination in director Pam MacKinnon's staging and the radiant presence of Phillipa Soo in the title role, I wish that were more of a compliment. For much of the musical based on the enduring 2001 French film, the fantasy appears to be aimed at the not-exactly-underserved audience of bright 11-year-old girls. But that is before the jolly cautionary rock song about STDs and before we find out that Amelie's love interest is a salesman in a porn store.
