Why don't Final Seasons bring in an entire batch of new characters, like "The West Wing" did, to successfully conclude a show?
There's so much pressure on writers to conclude their series, trying to stay true to the story and its characters - as well as to the fans of the show.
Most fail. A few succeed.
(Apparently, "The Boys" is currently going through the former currently.)
And yet I always think of how successful the Final Season of "The West Wing" was, by changing focus to a whole batch of new characters into the story, to continue the original story long after the actual show has finished.
From that final season, it seemed obvious to me that TV shows should do this. It may seem like a shortcut, may even be a cop-out. But I look at example of "The West Wing" and think its the most obvious thing to do that will instantly be successful.
Granted, you need heavyweights like Jimmy Smits and Alan Alda to overtake Martin Sheen and Alison Janney, to successfully transition. But there should be no reason why any TV show doesn't bring in heavyweights as new characters to continue the story after the actual show has concluded.
