Vieweship means virtually nothing to the network, its the demo that matters, and the muppets started out very strong with a 2.9, week 2 saw a large decline to a 2.0 which is still a very good rating, this week it got a 1.7, and if it stays in this range then it will be fine, Fresh off the Boat got as low as a 1.3, and was renewed, but if it consistently gets any lower than 1.4 every week, then it might not be a sure renewal, but it is owned by ABC studios, so it has an edge, I mean Agents of Shield got a 1.59 average last year, if the muppets can do better than that for its average, then it will probably be renewd, keep in mind that the first season of the goldbergs had similar ratings drops for its first 3 episodes, but still got a renewal.
