If I had a magic wand I would Give Mother Boswick a weird story to slowly spin out for us over the course of the show. As a kind of through-line, just to give it a narrative spine. But that’s not an “improvement” to offer. That show doesn’t need any improvements.
My overall impression
I had a blast from beginning to end. The crowd-work was seamless and went with the character and the show. I loved the hint of menace that Mother Boswick just barely kept out of site.
