The musical Matilda is based on the book by Roald Dahl. It is pretty similar to the book, with the exception of a side plot about a story that Matilda tells. That part was a little bit annoying, but altogether this musical is amazing. The music, written by Tim Minchin, is probably the best part, especially the songs When I Grow Up, Naughty, and Revolting Children. Matilda the Musical is definitely worth seeing.
