4 or 5 years ago, I saw The Steward of Christendom at the Mark Taper Forum in L.A. It wasn't very good, boring, hard to follow, dense dialog, meandering. At intermission, probably at good 50-60% of the audience left and that estimate might be low. I moved down from the 7th row to the front row which was now largely empty, not because I was enjoying the show but because it was a rare opportunity to watch a mere 10 feet in front of me, one of the greats of American theater, Brian Dennehy pour every last ounce of his being into a role. He obviously saw the many empty seats but it didn't matter, he gave everything he had to give. It was worth every moment of my time to watch this master work even if the play was a complete bore. For me, there's always some reason to stay.
