It seemed the sky was the limit for this US drama when it hit screens in 2011. Claire Danes was outstanding as the brilliant but troubled bipolar CIA agent Carrie Mathison and Damian Lewis almost as impressive as haunted hero Nicholas Brody.

Now, here we are at the season three finale and the characters – and series – are at another crossroads. Will they choose the path to Homeland’s redemption?
