The writers make a world of a difference in the development of the plot and all other subsequent sub-plots that may become involved in the course of the performance of each episode. The choice of personnel that play the parts and how they have melded the characters in the dynamics of the dialogue presented. How they project not only the professional dynamics but also the personal. Even with the characters that have been written out the writers have done an excellent job in how they have handled the logistics of the dynamics as they have introduced new characters. For the four star rating, I still question as to what demographic that the Amazon editions are to be marketed to. These are not family friendly for there are F-Bombs and other vocabulary that are not child friendly. Even a PG-13 rating is an inadequate caution.
