I thought the stories were phenomenal and was most enthralled by the one called Owls. I felt it more than remarkable that Mr. Gaiman did his own reading and found that aspect the most interesting of all. I loved this.
Ray Bradbury is a Grand Master of Science Fiction; this is a set of 13 of Bradbury's stories adapted to radio. The adaptations and the productions are great.
The selection of 13 stories are pretty diverse; some are hard-core sci-fi, other are more fantastic ("There was an Old Woman," "The Wind"), and some of them aren't necessarily sci-fi (or fantasy) at all ("The Screaming Woman," "The Ravine"). As is often the case with Ray Bradbury, the sci-fi/fantasy elements are often peripheral rather than key to the "real story," namely the psychological examination of the characters.
These were originally 13 28-minute radio shows, which makes for a few production "funnies." Each chapter is it's own radio show, with an opening intro section (which perhaps should have been edited out) and closing credits. Also, one or two of the stories (especially "The Happiness Machine") are clearly being stretched out to fill up 28 minutes.
I enjoyed "Bradbury 13" but didn't outright love it. (I could probably say the same about many of Ray Bradbury's works that I have read.)
