The first few shows were good, exciting cases, and good stories. Then the shows went from about 90 minutes to about 45 minutes, and the stories became simpler and shorter.
As the stories got simpler, they seemed to begin taking a long time to state the same things over and over. The later episodes contained a lot of unnecessary script, said three different ways by three people, and that, if removed, would shorten the show to about 25 minutes.
I believe the star of the show had two or three really good landmark cases, but after presenting those, they decided to continue the series with all his lesser cases as well. They seem to need to refer to the previous landmark cases also, as they don't have any juicy cases remaining.
