It is absolutely insane to try and explain or summarize it. The Unicorn's dramaturg did a brilliant job.

This production is co-created with UMKC and it is absolutely well-done from the set to the costumes to the acting. The start, however, is Manon Halliburton. She gave a chilling monologue delivery at the beginning that set the tone and description of the entire apolocolpyse. If she didn't do her job on point, the entire first act would have been off kilter. She absolutely nailed it. I would highly recommend any aspiring actors watch her from start to finish with her physicality and her voice control - she is a force. Matthew King's over the top humor in the second act was a surprise. He over-played in just the right areas. As a team, the entire ensemble had to ebb and flow between multiple changes, both in character growth, while almost playing themselves as a morality play. This is extremely difficult and demanding work. They did an outstanding job.
Word of warning, the Simpsons music will be in your head for a week afterwards.
