The Hunchback of Notre Dame, currently being presented at the Timber Lake Playhouse, is a little bit Jesus Christ Superstar, a little bit Frank Wildhorn, and a whole lotta Les Miserables, but it has a narrative structure and momentum that's all its own, and it's continually surprising - I can't recall the last time I felt so alert at the theatre. (It helps that this musical adaptation of Victor Hugo's novel is unfamiliar to most of us, having been produced only once before - at the Drury Lane Oakbrook Theatre - in 1994, and having gone through extensive revision since then.)
