It is looking increasingly unlikely that True Detective will be back for another season. The police drama’s first season won huge acclaim for HBO in 2014, but last year’s season two was considered a great disappointment. It has now been reported that the cable network may not move forward with season three.

According to The Hollywood Reporter, HBO’s new head of programming Casey Bloys is favouring a brand new show from creator Nic Pizzolatto over another round of True Detective. Pizzolatto has a development deal with HBO, which runs until late-2018.

In January, Bloys’s predecessor Michael Lombardo took the unusual step of speaking publicly about season two’s failings. “When we tell somebody to hit an air date as opposed to allowing the writing to find its own natural resting place, when it’s ready, when it’s baked–we’ve failed,” he told The Frame. “I take the blame. I became too much of a network executive. We had huge success. ‘Gee, I’d love to repeat that next year.’

“Well, you know what? I set [Pizzolatto] up. To deliver, in a very short time frame, something that became very challenging to deliver. That’s not what that show is. He had to reinvent the wheel, so to speak. Find his muse. And so I think that’s what I learned from it. Don’t do that anymore.”

Season one of True Detective starred Matthew McConaughey and Woody Harrelson, and was entirely directed by Cary Fukunaga, who won an Emmy for his work.

The second season featured Colin Farrell, Vince Vaughn, and Rachel McAdams, and even at its viewer peak, fell short of what season one had achieved. The final episode was watched by an audience of 2.73 million in April, a 22% drop from the season one finale the previous year.
