I agree Hostages isn't likely to last very long. I thought Brooklyn Nine Nine was okay but also, I don't see it surviving very long.
Plus 80% of those ten thousand sitcoms will be insta-cancelled and the remainder will last ten seasons.
I liked Agents of the Shield. I think it's going to be one of those shows that's on the bubble every season but manages to struggle out a few years on a small devoted fanbase like Chuck.
