Repeating Plot Formula
I've been re-watching "Lou Grant" on American Life Network for the past year and while I still love the show, it's incredible how often they repeat the same plot formula. Nearly every episode has an "A plot" focusing on Billie or Rossi investigating a controversial story, with Lou's help. Then there's the "B plot" in which one of the minor characters (Charlie, Mrs. Pynchon, Donovan, the Animal, or Adam) was directly or indirectly being affected by the same issue.
The reason was obvious - the writers could give us both a hard-hitting, objective view of the issue, AND they could also give us a more subjective, emotional take on the same topic. Rossi could be out getting facts about mental health issues affecting Vietnam veterans, and then we can see the Animal dealing with his flashbacks from the war.
Unfortunately, this led to serious credibility issues in what was supposed to be a realistic show. I mean, how much drama could really be going on in these peoples lives? How objective could the Trib be if its staff members were personally involved in so many of the stories it was covering? It also sometimes forced the characters into acting in ways that were completely inconsistent with their established personas - like the episode where level-headed Donavan is in a weird state of denial about his mother's terminal illness.
