Ouch! I would hate to have anything to do with a performance that causes a critic to break down and confess, in print, that he's abandoned his longtime policy of not walking out on a show before the end:
In the past few years, I have softened my stance on this issue because
I have come to believe that there is a point of no return, when hope of
a recovery is lost. When the patient dies, it’s not unreasonable for
the rest of us, especially those who had to listen to the yammering
fool, to try to move on.
