???Nightfall,??? by Isaac Asimov, is one of the greatest science fiction short stories ever written. The premise is, what happens on a planet where total darkness occurs once every two thousand years? This adaptation is pretty good, if you don't mind old-fashioned radio acting. This is worth more than $0.95 (or $0.66 for members).
I'm a big fan of Heinlein, but this production really didn't do his work justice. Obviously any radio production has to shorten and eliminate things but I just felt that the stories had become flattened to the point where they were little more than pulp. I also think that the quality of the production is very poor. Yes, they were all obviously produced a long, long time ago (I'm guessing 50s or 60s) but it should have been possible to clean the audio up so that it's more easily understandable.
