@ronsboy67 True. Although in my case, if a story, or the world they built, has potential, I want them to create additional seasons.
It is like reading novels. If the author did well with the first novel, making the worldbuilding and story enticing and engaging, I want to see Book 2, Book 3, and so on.
For example, “IRIS”. It was good they created “Athena: Goddess of War”, a spin-off, and “IRIS 2” (with elements from the first season and Athena).
Or, say, “Missing: The Other Side”, they created a Season 2 which was perfect for the franchise and what I believe to be the goal of the writer: to tell the public we should care about the missing persons cases. (They don't have plans for a Season 3, which is a good decision, because it will dilute the message of the franchise.)
And the “Strong Woman/Girl” franchise, was itself a good execution. They created two parallel stories, and they plan on creating a Season 2 for each, and potentially introduce another parallel story “Strong Man/Boy”. They're expanding the universe, and leaving potential new seasons open.
While it appears to be “Westernizing”, for me, if the fictional world they created is very good, then they shouldn't avoid creating a new sesason. It doesn't have to be 3-7 seasons more. Again, depending on the story, like in “Missing: The Other Side”, 2 seasons is perfect for the story.
Or, they can do the “Strong Woman/Girl” approach, create parallel stories. Or, the IRIS approach, spin-off, and then later combine the spin-off with the main.
