It is seldom that one sees a really-good adaptation of an H. P. Lovecraft story, especially when a writer tries to improve it by adding a love theme or changing the point of view for a more modern technique. I have just experienced one of the exceptions, a radio-drama version of "The Colour Out of Space." I very strongly recommend it to any listener -- it manages to be better than the original tale, through extremely good acting and some minor changes that make the story more plausible and terrifying. Even better, it keeps the original 1880's setting for the main and 1920's setting for the framing story.
