I'm not sure how it will work long-term either, but if TV has taught me one thing, it is that a concept can be milked dry for season after season no matter how impossible it seems at the beginning. This would be great as a movie, but I'm confident anything with Kiefer Sutherland will be good for at least a full season.
Other than that, I don't see how anyone could watch that first episode and not be excited to watch more. That was some pretty intense shit, and I lapped up every second of it and wanted more when it was done.
Also happy to see that his aide, who was Siobhan on Supergirl, is getting more work because there's something about her that I find incredibly attractive while still coming off as sophisticated. Hell, Kiefer's wife and the FBI chick are hot too, just like in every show pretty much.
The son at first reminded me of that douche-fuck kid on Fear the Walking Dead, but I'm hopeful this one won't be a mopey fuck that I want to die every episode. Nope, just the druggie kid angle, but what can you do? Little girl is cute.
