It is possibly the best play I have seen in New York. It helps that I went in with low expectations, but I think it would survive even high expectations (which I hope to provide).
The premise: a callous professor of poetry receives treatment for ovarian cancer. Played by a former Sex in the City cast member.
You can see the source of my low expectations.
The author, who won a Pulitzer for the play in 1999, has yet to produce another work and continues her job as a primary school teacher in Georgia.
If you are not in New York, there is a television version that is apparently good.
