Well, I think this primarily applies to “Act 2”, which I would categorize as hours 16-24 (11 PM to 8 AM).
In season 2, I think Act I holds up quite nicely, and has a much more urgent premise (finding the nuclear bomb). The second part (the response, and impending war) was stretching it for me. And the ending of “Act I” was incredible, I thought (episode 15: “10-11 PM”). Very chilling ending.
Well, the exception to this, of course, is the Kim subplot. I think she made one (count them… ONE) smart decision in the first 15 hours of the show, and that was pulling the gun on Creepy Guy that she almost hitched a ride with. But then she was back to dumb-dumb decisions (starting with getting out of Nice Lady’s car and wandering on her own again on the highway).
er… wouldn’t that be “another 11 hours”?
Season 1 – I agree that they probably didn’t decide to make Nina the traitor originally, but I do think that the “almost killing Nina” bit works fine, because that was due to bad-guy-Ira-Gaines, who only knew about Jaime as his inside contact. After season 2, we still don’t know who Nina really works for.
And BiblioCat – Nina wasn’t really the mastermind behind it all, anyways – she was just taking orders from somebody else, and it seems this somebody wanted her to help the Drazens at this point.
