Stuff like this is really nice to hear, from a reader:

Dear Mr. Goldberg,
I am a subscriber and a regular on- line reader. Last year I received the article in the magazine and used it in my English class. This year we are viewing the movie and critically reading your article. I’ve asked students to look up various allusions, especially the existentialism references and the Sisyphus reference. We have just finished a unit on Marlowe’s Faustus and find Phil’s abuse of his singular powers similar to Faustus’ when he used his limitless power to play tricks on the pope and to play other farcical low-brow jokes. Happily, as you have said, Phil is redeemed; Faustus is not.
You have helped me immeasurably to understand a movie and its message. Thank-you.
