A second season has not yet been confirmed. HBO is certainly interested, which is unsurprising given how popular the show is and the audience only continued to grow as the season progressed. They are waiting for Nic Pizzolatto to turn in scripts before giving season 2 the green light. That's a fair ask as it will be a new story, a new cast and a new setting.
I like the anthology format they've chosen and hope they're able to pull it off successfully, it's something I'd like to see more of, if done well. It's tiring to consistently see the model where popularity is found and the show is milked for all it's worth as a response, often overstaying its welcome. I've long been a fan of series where the story was planned from the very beginning and had been plotted and paced accordingly.
Comics, anime and live-action TV shows have done it successfully. TV mini-series are the only instances I can recall that have been enjoyable – American Horror Story has tried this, but that show is best forgotten. True Detective looks to be an extension of the mini-series by fitting within a theme. It's a model with a bright future and plenty of potential, all that's needed are some daring and talented individuals to lead the way.
On True Detective, I've got something that I'm sure at least one person here will understand and enjoy.
New episode today too. Woo!
