Homeland TV series to end in season 8
Based on an Israeli series called Prisoners of War it had an amazing opening hook with an American soldier (Damien Lewis) coming back from being captured by al-Qaeda to a heroes welcome in the USA. Only a bi-polar analyst (Claire Danes) believes that he might have been turned by the enemy.
That was plenty of fodder to begin with but the show has gone off the rails a bit since then, losing the clear focus which it had at the beginning. Still Showtime has faith in the production, recently renewing it up for seasons six, seven and eight to bring it up to at least 2019.
