I saw this show in 2018 in cabaret venue and it was spectacular then, and it was the same now on screen. The comedy is a hilarious reflection on the pains of the current culture of narcissism and everyone having 'main character syndrome' or wanting to have it. Her voice is gorgeous, flexible and clear. The opening song is almost a thesis statement for the entire show. She is a victim of herself, and presents her unhinged spiralling with espirit and does self-deprecation in a new way that I have not encountered before.
It is odd to read some of the other reviews here, saying the she has a bad voice, because that is blatantly false (and makes the reviews seem entirely disingenuous). Also I wonder if these reviewer have ever been to a cabaret, if they understand the tradition she is working within is not stand-up. It is cabaret! Cabaret is bawdy, that is one of the main features, a shock for the puritanical undercurrents that persist in American society. Cabaret is gleaming, liminal, glittery, grubby and funny; and Catherine Cohen imparts these tones gorgeously.
