Into the Woods is a kind of conglomeration of several traditional fairy tales. They all link together in a complex web of intrigue. The plot centers around the main characters' wishes. The Baker and his wife wish for a child. Cinderella wishes to go to the festival. Jack and his mother wish Milky White (their cow) would give them some milk. The witch wishes that she was young and beautiful again. Little Red Riding Hood seems just to wish to cram her face with as much sweets as possible. All these plots come together in an interesting and comical way.
The music (written by Stephen Sondheim), though not compositional anywhere near the level of Andrew Lloyd Webber's music, has it's certain charm, and most of it's hummable. Many a time have I found myself whistling those ditties.
