If you've enjoyed Polanski's "Carnage" here you'll find a similar stage performance with a little more comedy and uninhibited characters.
2 couples of friends unexpectedly spend a night talking about their lives (or rather arguing and hurting each other) as a consequence of an affair involving one of them. Despite 5-10% of the film is a little weak from a writing and/or acting perspective (which is fine given the intensity of the dialogue and the width of topics), the rest is quite enjoyable, interesting and realistic.
If you'd like to see your worst self in a mirror, and enjoy how bad, miserable or funny you would sound, give it a try. If you believe that your life is empty, inauthentic and it's too late to do anything about that, give it a try: you'll feel better. If you believe that your life is well ordered and goes on according to plan, avoid attempting to answer the questions that raise during the view: you'd likely ruin your peace of mind.
Good job.
