Supernatural creator Eric Kripke has hyped season five as: "The war everyone's been waiting for."

So far, viewers have been excited to see how this has all come together - but should they also be worried? Kripke has said in the past he only sketched out five seasons worth of storylines for The CW drama.

Fortunately, though, network president Dawn Ostroff says Kripke is open to the possibility of a sixth season.

“I think he’s in that state of mind,” she told Entertainment Weekly. “I had lunch with Eric the other day and he’s really excited about the show right now. I think he feels this season has been really satisfying for him. He’s certainly not running out of ideas by any stretch of the imagination.”

Ratings have been up this season, too, as Ostroff is thrilled with the change in its demographic.

“We have more young women coming to the show than ever before," she said. "There aren’t a lot of shows that you can say are doing better in their fifth year.”

Supernatural returns with a new episode on January 21.
