I saw Tatiana Maslany as the guest actor and enjoyed it very much. I think it's true that it varies quite a bit depending on who the guest actor is that night. Tatiana was clearly moved (she cried more than once during the show), and I felt that her emotional connection to the material and to Soleimanpour helped draw the audience into it as well. Some parts worked better than others (I wasn't crazy about most of the audience participation segments), but overall I thought it was a lovely, moving play. I do think the guest actor you see plays a big role in your enjoyment, though, so I recommend looking at the calendar in advance. (I chose to see someone I'm a huge fan of, and I realize that impacted my reaction.)
