The 12-episode 6th season of Homeland aired in winter and spring of 2017. This season brings the show back to the United States. It is specifically set in New York and has a few different intertwined storylines, the main one being an attempt at taking down the President-elect. It is heavily influenced by the political climate and events of the past few years. The stories are well done, the acting is top-notch, and I do not think the show is overly preachy with the political elements as some shows can be. It did incorporate an Infowars-like radio show and a social media troll farm into the story and definitely used the real-world political divisiveness and hatred that exists to tell part of the story.
Ultimately, the season is very good. Rupert Friend as Quinn is really the standout this season. We learn in the first episode that Carrie did not end up pulling the plug on him, and when he comes back, he is a shell of his former self, dealing with, among other things, PTSD. He has to go through a range of emotions with the character and does it very well. While he is (in my opinion) the show's "backbone" this season, all the main and supporting actors did a great job with their material. Homeland is definitely a show that has had its ups and downs. I do think they struggled to end the Brody storyline, but now, being a few seasons removed from it, I think the show has recovered quite well. It could have easily gone in the tank after the first two seasons when all was revealed (and there are definitely some out there who think it did). But if you gave up on it during season 3 or 4, I think it has recovered nicely the past couple of seasons and is well worth taking a look at again.
