Many have tried to reveal the darkness behind our most beloved fairy tales, but few did it better than Stephen Sondheim. The first act plays straight, as familiar faces like Jack and his Beanstalk, Cinderella, and Little Red Riding Hood seek new lives. The second act shows the truth behind the old adage: Be careful what you wish for. It’s an incredible depth of story, accompanied by the always-interesting musical turns of a Sondheim score. Things fall apart, they’re rebuilt, and everyone’s changed in the end. Enjoy your travel into these wild woods while learning that fairy-tale life isn’t all it’s cracked up to be. – Cat McCarreyThrough Sept. 29.
