It is musical but the singing is tastefully done in the 'stressful' parts. It takes a difficult topic and helps you get through achieving a better understanding of it in the end. So there is redeeming value here. I had never seen nor had any knowledge of the play prior to seeing this film. More about the musicalness: I disagree with another review that said that the music did not 'fit in.' I think what made it fit was the fact that the fact that 'singing' was going on was not acknowledged by the other characters. It looks like they are just hearing the dialogue. That suited me. i.e. no 'on-screen' musical numbers where there is singing back and forth except one beetween 2 people. Otherwise if you want to see it live - a play - then do that.
