After ending its first season on a cliffhanger, Amazon Prime Video has canceled the show, according to Variety.

“Countdown,” starring actor Jensen Ackles, followed a Los Angeles Police Department detective, played by Ackles, investigating the murder of a Department of Homeland Security officer.

The show premiered in June and made a brief appearance on Nielsen’s top 10 streaming originals chart, according to Variety.

The show’s finale aired on Sept. 3 and featured a cliffhanger regarding the fate of one of the show’s main characters.

In a post on Instagram, Ackles shared his thoughts on the show’s cancellation.

“As some of you may have seen already, ‘Countdown’ did not get picked up for another season,” Ackles said. “Amazon’s gonna let it go, and it’s a bummer because I had such an amazing time making that show. Had an absolute blast with the cast and the crew.”

The show was created and written by Derek Haas, and also starred Jessica Camacho, Violett Beane, Elliot Knight, Uli Latukefu and Eric Dane.

“I’m thankful for the experience,” Ackles said. “I really am. We’ll see you down the road on something else.”
