Update, after watching all of Season 1: Some scenes have outlandish dialog and the transitions are either clunky or too speedy. Here's what I've decided: I'll try to approach certain scenes in a similar way as I would a comic book. If there are things which don't echo traditional "reality", I'll attempt to keep moving forward.
Original review: I almost gave up on this show after two episodes. There was something in the way the plot unraveled which felt a bit overwrought. I'm glad that I stuck with it, and the writing seems to be getting better, or maybe I was in a less receptive mood when I first watched. The entire cast is well placed, with standout performances from Sterling K. Brown, Julianne Nicholson, James Marsden, and Aliyah Mastin (as the daughter of Brown's character). Gerald McRaney gives his role gravitas and interesting twists. Marsden as the president has a complexity which I did not expect. While I've seen him in other productions, this one stands out. The effective soundtrack is sometimes subtle, and the set design is more than apt. My prediction is that this series will resolve itself within 3 or 4 years. Overall, this series is worth a watch.
