Ryan broke the news early Sunday that the rookie drama would not be returning.

Mad Dogs is one and done at Amazon.

The freshman drama will not return for a second season, executive producer Shawn Ryan announced Sunday on Twitter.

In a series of 20 separate tweets, Ryan revealed Amazon's decision not to move forward with the series despite Ryan claiming he heard the show had "better streaming stats than many other Amazon shows."

Ryan also acknowledged that the series was originally intended to be a 10-episode limited series. However, in order to get the series made at all, Amazon wanted to know that there was a possibility of future seasons.

"[Creator and executive producer] Cris Cole and I said we thought there could be but we should have that conversation on if and how after the season was over," Ryan continued. "We had that conversation on Thursday with [Amazon Studios head] Roy Price and company. Cris and I laid out a story for Season 2 we believed in. Ultimately, Amazon didn't want to make that story and we didn't want to make the kind of story they wanted us to make."

Ryan said it was right to stay true to Cole's original vision, rather than to make a "watered down" version of Mad Dogs simply to get a season two pickup.

Mad Dogs, from Sony Pictures Television, centers on four former frat brothers who travel to Belize for a reunion, but their luxury vacation is interrupted by a series of wild events that expose dark secrets, deception and murder. The series starred Ben Chaplin, Michael Imperioli, Romany Malco and Steve Zahn and premiered on Amazon in late January.

Based on the U.K. series, Mad Dogs was previously developed at FX before landing a series order at Amazon. Cole, who created the original series, penned the script and exec produced alongside Ryan.

Mad Dogs is only the second Amazon original series not to receive a second season, following the 2013 comedy Betas. The company, which is known for releasing dozens of pilots for viewers to watch and vote on, has been ambitious in expanding its slate of original series, thanks to the success of Emmy winner Transparent as well as Golden Globe nominee Mozart in the Jungle. Last year, Amazon picked up its first drama straight to series, David E. Kelley's legal drama Trial.

This is the latest misstep for Ryan, who enjoyed breakout success as the creator of the acclaimed FX drama The Shield. He executive produced CBS' Beverly Hills Cop pilot that failed to get a pickup, and before that he served as showrunner on The Last Resort, The Chicago Code and Terriers, all of which were canceled after one season. He is exec producing Netflix's hip-hop drama The Get Down, which premieres in August.
