The simplicity of the set, the costumes, and the tone established by silent cows as the line progressed.
What I didn't like
Sorry! I was charmed by it all.
My overall impression
The solemnity of the dialog was brought to life brilliantly by Betsy and Patty. A day later, I am even more struck by how the actors, in cow costumes, on a nearly bare set, completely engaged me with their expressions, body languages, tones, and non-human (nor bull-like) movements into passionately caring about what could have been a dry exposition of popular psychology and philosophy. I am old, and cry at the drop of a hat. Still, I was in tears and on the edge of my seat near the end, when Betsy and Patty did their Alphonse and Gaston. I thought the horror of what Patty observed would be the sad climax. But the ending was better. Patty’s slight head turn, and grin, was perfect.
