This season is worryingly close to real life events that have happened over the last few years, - terrorists attempting to blow up a European Underground, Chemical weapons, Syria. That said 11 of the 12 episodes keep you glued and wanting more.
There is plenty to mention but I do not want to spoil any of the plot. Claire Danes (Carrie) and Mandy Patinkin (Saul) are the two main characters again who deliver in every scene they are in.
My worry is that Homeland has just been through Season 5. I am not sure how many more times Carrie and Saul can save the world albeit the state of today's world mean the story lines are never too far away.
(Plot spolier) - I hope Rupert Friend (Peter Quinn) makes a recovery from what appended to him. He too has grown into the role as a Black Ops agent but was massively under utilised in Season 5.
Also the story writers need to work on building up the to the final episode. Similar to season 4, the last episode (12) is a bit of an anticlimax (everything exciting having happened in episode 11)
