Why do filmmakers delay the announcement of a second season for a very successful tv show. 

I don’t know all the answer, but I think one of it is because they really need to see the end from the beginning. 

Announcing a new season makes no sense until you know how it will end. And that’s where the hard work is, they need to craft the end of story from the beginning. 

If there’s no logical conclusion for the story, there’s no announcement and there’s no production.
