It is really interesting look at at some very familiar story structures, the "Cinderella" story, the "Disaster" story, and then real life.
This is an interesting way of looking at Narrative arcs. Personally, as a visual thinker, I find this useful especially when looking at longer improv formats with more than one connected scene.
I like the idea that we can, in improv, take explore these high's and low's easily. There are no restrictions, we can go anywhere, anytime, and be anything.
