Just binge watched 5 episodes tonight. Frontier must have updated its on-demand library in the last week, because it was missing episode 5 for the longest time so I was stuck (why Frontier decided to only initially add every other episode to its on-demand library was mystifying).
Anyway, this may be the best season yet. The show is a lot better without Dana, and the Pakistani's are hard core gangster bad guys, much tougher and scarier than al Qaeda or the Iranians. The ISI chick is awesome. As an aside, I am willing to start a collection to increase her contract with Showtime if it will get her to take her clothes off. I think Khan doesn't make it out the other side. Tasmeen has figured him out, and she will take care of him in time.
This is the first time in the Series where you really feel like the bad guys have the upper hand every episode, which makes it much more fun to watch. The reality is that a foreign intelligence service picking up a former CIA chief would border on an act of war, but as a plot twist, it was definitely interesting.
