I enjoyed seeing the relationships evolve as the characters shared their feelings and secrets. The musical aspect fit in nicely.
What I didn't like
There were a few minor issues with the singing- an off note here, getting too quiet there, and one odd transition to an almost operatic style for a phrase.
My overall impression
Despite including zombies, this was a really lovely show about family relationships and how we view the people around us. Thoroughly delightful.
