"I'm the end of the line; absurd and appalling as it may seem, serious New York theater has died in my lifetime"

This quote by Arthur Miller is a reflection on the state of serious New York theater in his lifetime. He is revealing his sadness and shock that the theater he once understood and loved has died. He is stating that he is the last of a generation of theatergoers and specialists, which the theater he knew is gone. He is regreting the fact that major theater has actually been changed by more business, less meaningful productions. He is likewise revealing his frustration that the theater he once enjoyed has actually been changed by something that he discovers absurd and terrible. He is saying that he is the end of the line, which severe New York theater has died in his life time.
