If you described the musical Into the Woods as a romp with various fairy tale characters who interact with each other in often amusing ways, you'd be right. You'd also be right if you said the play is a journey into the dark place where all our demons reside and that you may emerge wiser, or not. This Great Lakes Theater production of the much-loved Stephen Sondheim musical bristles with invigorating movement and features a raft of fine singing voices.
