Something that I was thinking of when comparing Designated Survivor and Madam Secretary as two similarly contrived network political shows inthispost.
The main takeaway is that DS basically seems to have a conspiracy plot it cannot escape, due to it being the main hook of the show (Madam Secretary on the other hand was able to just become a general politics show and let go of the conspiracy stuff). Yet, that plot was adequately finished at the end of S1 so the show risked becoming just another politics show, which would make the main hook obsolete. As a result, the show basically has to continually whip **blip** out of its ass to keep the hook (and Maggie Q, whose main relevance was to the now irrelevant conspiracy arc) relevant.
I'm wondering about other shows that started with a main hook or premise that they just totally resolved or made irrelevant but kept going. How did they fare after? Did they get better? Worse?
