I guess the issue for me is that "confronting demons" just isn't my scene. So, it's issue of "it's me, not the performance", with the result that I was left a little cool by the play.
Edit - In thinking a little more about the play's lack of appeal, I guess the issue is that most of the play is taken up in identifying just what the "demons" are. They gradually emerge, bit by bit. Once the issues have been identified, there's not much more that can occur, and the outcomes were, perhaps, inevitable.
