For one thing, it's a musical. It's a smorgasbord of entertainment.
Musicals are an iffy thing.
Very few of them appeal to me. The classics are already hard to beat-The Sound of Music, Mary Poppins, My Fair Lady, Fiddler on the Roof, and The King and I are among my favorites. Although they're still wonderful today, these musicals are favorites of my childhood, so it's mostly sentimental affection that I have for them. These days, we're a much tougher, more sophisticated audience. We expect a lot more from the silver screen, and we usually associate musicals with Broadway-live, not celluloid.
