Jensen Ackles is sharing his reaction to the news that Countdown was not renewed at AmazonsPrime Video for a second season.

The crime thriller debuted its first season in June before wrapping up its 13 episodes in early September following a weekly rollout. The series followed LAPD officer Mark Meachum (played by Ackles), who joins a secret task force to investigate a suspicious murder, but uncovers a sinister plot that requires the team to unite and save millions in the city.

On Friday, Prime Video announced it would not be renewing Countdown, despite it spending a short time on Nielsens top 10 U.S. streaming charts over the summer. Ackles took to his Instagram to share his thoughts, saying, As some of you may have seen already,Countdowndid not get picked up for another season. Amazons gonna let it go, and its a bummer because I had such an amazing time making that show. Had an absolute blast with the cast and the crew.

The Supernaturalalum went on to express his appreciation for creator Derek Haas and the shows writers, as well as Amazon for giving us the opportunity to make the series.

Sometimes you can set out to do your best and check all those boxes, and ultimately its out of your hands. Thats the way it goes in this industry, Ackles added before concluding, Thats the end for Mark Meachum. But Im thankful for the experience. Well see you down the road on something else, I guess.

Countdown also starred Jessica Camacho, Eric Dane, Violett Beane, Elliot Knight, Uli Latukefu, Rachel Armstrong and Bogdan Yasinski.
