With a strong supporting cast (who gets tired of Carrie Coon? If so, you are fired as an audience member), this is truly the Mackenzie show - an often funny, sometimes frustrating, ultimately cathartic - for some, confusing - end song. Think train-wreck, one-hit-wonder, musician trying to stop her ex from getting engaged, but somehow has to get across town while her car is in the shop in her vomit-covered catering uniform from a black-out night before.
