Part 1 is the first act, somewhat expanded. The additions are pretty seamless and add a bit to the story. Its been a long time since I saw the play, but there is only one part I was sure wasn’t in the original
spoiler
(A Cameo with Kristin Chenoweth and Idina Menzel)
If you are into the play you would probably like it. I went with my wife and daughters and they loved it. I found it enjoyable enough. As someone who isn’t super into the play, it was paced well, with some good comical elements.
My brother loves his xterra so much he is on his 3rd (first was an accident, second went to the ex in the divorce). I rarely ride in it, but it seems kinda like a rattle trap to me. I dont know how much of that is his abuse and how much is the car.
