Here's another tale that could have ended very differently. Matilda could have gone the way of Carrie, using her powers to destroy others and herself. Instead she makes the choice to use her powers for good.
Matilda and her mentor, Miss Honey, are both victims of abuse. They handle their situations very differently. Miss Honey has stayed with her abuser and become a self loathing neurotic. Matilda fights her fate and saves Miss Honey from hers. Deep topics for a so called "children's musical."
"Just because you find that life's not fair it
Doesn't mean that you just have to grin and bear it
If you always take it on the chin and wear it
Nothing will change."
Tim Minchin's lyrics are dense and clever. They were also left at the mercy of child actors and theatersound systems. A common complaint, particularly on the American tour, was that audiences couldn't understand the words. I've yet to hear the score of his new show, Groundhog Day. I'll be curious to learn if he slows the rhythm of his lyrics a bit so that more can be taken in on a first listen.
