I don't know how it's doing in ratings (I am enjoying it, though), but with what ABC is doing to Designated Survivor, they should be the last to question "what happened?" if the audience numbers plummet and the show is a one and done. Tonight the show had its Fall Finale, on December 14th. It won't come back until some time in March, three months later (depending when in March). I remember a similar break is what ruined the momentum Revolution had during the first half of that season. It limped on to a cancellation (after a, rather surprising season 2 renewal). I could see this happening with a show that's been around and has a massive fanbase, but for a freshman show, that is quite a gamble. So many of the other ABC shows, I've heard January (or in some cases, February), but not March. If this was a one season only show (which is something I would love to see more of, but that's a whole different can of worms), I think that would make it easier to swallow.
