There was a time when he was the most famous playwright (in the English language) in the world. He is most famous for Pygmalion (1913) which became the musical My Fair Lady. Much better than that one (in my opinion) were Saint Joan (1923) and Misalliance (1909). He also wrote a play with a great F/m tickle torture scene in it, Great Catherine: Whom Glory Still Adores (1913).
I hesitate to post it here, because I don't want to inject politics into this section of the TMF, so I will leave out the author's name.
It was It Takes a Village published in 1996.
King has written some books that I greatly enjoyed, notably Needful Things and Gerald's Game.
He has also written some real stinkers. The Tommyknockers was awful as was Christine.
So to me he is woefully inconsistent.
