“Roald Dahl’s Matilda, the Musical” is an adaptation of the Broadway musical, currently streaming on Netflix. Like most of Dahl’s works it is a macabre version of childhood with a whimsical, off beat tone. (Think Willy Wonka.) Matilda is a prodigy and is sent to a school that is run like a prison by a tyrant of a head mistress who is played by Emma Thompson. The child actors are quite good, but Thompson steals the show. She is so over the top that you can’t take your eyes off of her. I enjoyed her performance a lot. An enjoyable piece of fluff. Go for the story and songs, but stay for Emma Thompson!
