Thanks for the link/information. They did have minute and a half trailers on iTunes and they sound basically like a radio drama featuring short stories from the series. I'll probably download the first one and see how it is and report back. My wife and I were fans of the series around the time it first came out and then lost track of it after S3. At some point, I plan on watching the series on Netflix and/or buying it on DVD and watching through the rest of the series.
Does the series get better? Or worse? Or pretty much stay the same? I thought that the first two seasons were really strong/entertaining. I felt that the Season 2 finale/Season 3 premiere was sort of weak.
