Sam and Dean are officially giving up the hunt for demons.

We've known for a few weeks now that the upcoming fifteenth season will bring Supernatural to a close, but there has been no indication why the hit series is ending.

Until now.

“This was a community decision. The network and the studio did not say like, ‘Hey, guys, get outta here! You’re done,'” star Jared Padalecki revealed at a fan convention for the drama series in Las Vegas of the decision to end the network's second highest-rated series.

"It wasn’t an easy decision,” co-star Jensen Ackles added.

“It was months and months, if not years, of discussion between [Jared] and I, between the rest of the cast, between the crew, between our writers, between our producers, between the studio, between the network.”

“Nobody wanted to see this show fizzle out,” Ackles added.

“I think that it was everyone wanting to do the biggest service to the show that we could by going out strong."

"It just seemed like the writing was kind of on the wall as to when that was happening. I think everybody kind of felt that it was coming soon."

"So it was just taking that leap of faith of going like, ‘Well, guys, let’s get out the paint and paint that finish line, and hold our heads high, because what we’ve accomplished is unlike any other.’"

Ackles went as far as comparing the decision to end the series as “if we’re driving the Impala, and we’re heading down the road, and it’s, like, left, you’re going to hit a ramp and go off a cliff, and it’s going to be epic, or right, you’re just going to run out of gas about 30 miles down the road in the middle of the desert with nothing around you. I’m like, ‘I’m going left. I want to go out with, like, pyrotechnics.'”

Fifteen seasons and 327 episodes is a lot, and it's excellent that the show remains one of the network's highest-rated series.

It's unclear whether past characters will be making appearances during the final season, but we should get some more word on that down the line.
