"Homeland" has dealt with controversial stories before but they draw the line when it comes to ISIS. Speaking at the opening night of PaleyFest in Los Angeles over the weekend, executive producer Alex Gansa said ISIS was too vile and there's no way they could humanize them. "We're one of the few shows that gets to really comment on current events. We take that responsibility very seriously," he said.

He explained as quoted by The Daily Mail, "It's a very good question because Homeland for the last four seasons has tried to portray our adversaries and tried to humanize them. And if you look at Abu Nazir, even look at Brody, or look at Haqqani this past season there was a real effort to make their concerns and their lives understandable. That is very hard to do with ISIS."

"It's very difficult to do because what they are doing on the ground feels so medieval and so horrible that you give them a platform on television I'm a little wary of; to try to make what they are talking about understandable or relatable is very difficult."

"Maybe this is too soon, Maybe we don't understand them well enough; It may be that they are just too evil to dramatize on television," Gansa added. "I think right now the intelligence communities, the United States government doesn't really even know how to deal with them on the ground right now."

In the next season, Claire Danes' Carrie will leave Middle East and quit CIA. It will take place in German two and a half years after things ended at the last season.
