I can't say I loved every minute of the musical, or that it totally changed my life, or even my opinions about the musical version of Matilda or the film version of Groundhog Day. But I certainly enjoyed it. It has a lot of strengths, and at least one number that I haven't stopped thinking about. Sure, there are weak links: the set and sound are both a little murkier than they should be at various points, and the whole production came off as a little too darkly lit. The first act gets a little bogged down with a lot of exposition and the constant repetition that's part of the fabric of the plot. And many of Minchin's lyrics and melodies just don't stick with me, even after repeated listening (truly, I tried).
But the cast is strong and committed. The car chase, done with little car puppets and black light, made me laugh, and there were some excellent stage tricks during the suicide attempts. And if you have never seen Andy Karl on stage, you're missing out. As Phil, the arrogant and condescending weatherman who learns to be a mensch by the end of the show, he's endlessly appealing. In everything I've seen him do, I'm newly struck by how gifted Karl is both as a verbal and physical comedian. Here, his talents and his charisma are put to excellent use, especially since he walks the same fine line Bill Murray managed so well in the film (and just as a general proposition): Karl's Phil is never enough of a smarmy, insufferable dick that you genuinely hate him, but he's just enough of one that his gradual transformation and self-actualization into a reasonably good guy remain consistently engaging.
Then there's the wonderful "Playing Nancy," which pretty much made the musical for me. Performed at the top of the second act with absolutely no fanfare by a secondary character who previously has been fooled into sleeping with and subsequently dismissed by Phil, the piece is beautiful, delightfully meta, and astoundingly forthright in its commentary. I loved it, I haven't stopped thinking about it, I listen to it often and fondly. Thanks, Tim Minchin. You might not be my alltime favorite Broadway composer, but with this song, you've earned my respect. Hats off to you for considering, even momentarily, the roles women play in the most heralded and blockbustery and revered of mass entertainments, which are ultimately and almost always about men--and for writing a song that doesn't flinch, pander, or condescend. I'd make like Bill Murray and sit through all of your future musicals twice in a row, anytime, as long as you keep writing songs like this.
