There is a niche that no one fills, that I'm hoping Netflix shifts into: "Popular series was canceled? Let's pick it up and give it a final season!"
They're doing it with Manifest right now. It was on NBC and canceled after 3 out of 5 planned seasons, and the creator was trying to figure out how he could finish the plot as a single movie, then Netflix bought it and gave him an entire 20 episodes to finish the plot - almost the entire two missing seasons. First half was just released a few days ago.
