The emotions that the actors brought to their characters, which kept the play interesting.
What I didn't like
I wished they would have been more agitated at the elevator specifically: punching the buttons, remarking about if someone is/isn’t coming to help, does the call box phone work?, try jumping up and down, prying the doors open, etc.
My overall impression
A slice of life of what it would be like trapped in an elevator for an extended amount of time. I think the actors did a good job of working together through the range of emotions that they were going through.
