The materials, the world building, the acting, the writing.
What I didn't like
Some lighting cues seemed off, but I saw the preview so that is to be expected?
My overall impression
I appreciated the world building very much. Before the show starts you “disinfect” your feet, a pleasant (or is it ominous) voice reassures you of your safety and reminds you of the hell that is outside, the materials on your chair establish apocalyptic details. And then it begins and the actors ARE SO GOOD. It’s funny, totally thoughtful and thought-provoking (sign me up?), and more moving than I expected.
