When Ethan Hawke made a surprise guest appearance in the penultimate episode of Reservation Dogs, it wound up being one of my favorite TV episodes of all time.

Co-written by Reservation Dogs co-creator Sterlin Harjo and star Devery Jacobs, "Elora's Dad" saw Elora Danan (Jacobs) meet her estranged father (Hawke) for the very first time. He introduces her to her half-siblings, and she catches him up on her life, including her plans to go to college. The episode proved intimate and quietly electrifying, one of the best entries in one of the best shows of recent years. And at its heart were two beautifully grounded performances from Jacobs and Hawke.

So imagine my delight when Harjo and Hawke teamed back up for Harjo's new FX series, The Lowdown. Then imagine my downright joy when The Lowdown turned out to be some of the most fun I've had watching TV this year.

What's The Lowdown about?

Described as a "Tulsa noir," The Lowdown stars Hawke as Lee Raybon, a rare bookstore owner, citizen journalist, and so-called "truthstorian" determined to lay bare the rot at the heart of Tulsa's most corrupt power players. (Lee is based on the late journalist and public historian Lee Roy Chapman, whom Harjo worked with previously.)

Among Lee's targets is the Washberg family, headed up by slimy gubernatorial candidate Donald (Kyle MacLachlan). Lee uncovers the family's connections to white supremacists in a major exposé, and just days after its publication, Washberg family black sheep Dale (Tim Blake Nelson) dies under mysterious circumstances. For Lee, that can only mean one thing: He's onto something major. So off he goes into Tulsa's criminal underbelly, a journey that could lead to a major bombshell (or more likely, to severe bodily harm).

The Lowdown is part neo-noir, part hangout comedy, and all delightful.

Lee's investigation prompts Harjo to have some neo-noir fun, drawing inspiration from '70s films like The Long Goodbye and Night Moves. Smoke-veiled conversations abound, along with clandestine meetings with Dale's wife, Betty Joe (Jeanne Tripplehorn), and PI Marty (Keith David).

The Lowdown's madcap mystery provides a change of pace from Reservation Dogs, as does its city setting. Here, danger lurks around every corner, often in the form of skinheads who are angry at Lee for… publicly writing that they're skinheads.

Yet even with its moody noir atmosphere, The Lowdown also preserves the hangout feel that made Reservation Dogs so special, especially in scenes Lee shares with his daughter, Francis (Ryan Keira Armstrong). Francis spends most of her time with her mother, Samantha (Reservation Dogs' own Deer Lady, Kaniehtiio Horn), but when she shows interest in helping Lee with the Washberg case, who is he to say no?

Lee and Francis' sweet dynamic bears shades of that of Elora and her father's: tentative bonding attempts, even as Francis wonders whether Lee is a full-on deadbeat. However, it's also a perfect showcase for The Lowdown's ability to blend its noir mystery with character-driven hangouts. Case in point: A father-daughter trip to a lake that doubles as a mission to find key evidence.

In a similar vein, The Lowdown somehow manages to capture the wide range of human emotion, all within its mystery framework. In Lee's nightcap with a potential suspect, what starts as a drunken hook-up morphs from an investigation to a fight to a soul-baring discussion… then back to a hook-up. Elsewhere, Lee's reunion with frenemy Randall (Peter Dinklage) kicks off an investigation and a soul-searching tribute to an old friend.

So as much as The Lowdown is driven by the central mystery of Dale's death and his family's shady dealings, it's also fueled by the poetry of who we cross paths with. Like in Reservation Dogs, The Lowdown builds out a community of fascinating characters who add oodles of texture to the show's version of Tulsa, from antique dealer Ray (Michael Hitchcock) to The Tulsa Beat editor Cyrus (Killer Mike).

Ethan Hawke is a hilarious wild card in The Lowdown.

At the center of these characters is, of course, Lee. And my goodness, is Hawke having the time of his life in the role.

Hawke plays his amateur sleuth like a total wild card. In some moments, Lee is effortlessly cool, rolling into investigations like suave is his middle name. In others, he's almost pathetic, running for his life after getting himself in too deep. Hawke's maniacal laughter after Lee's escapes or major discoveries is a forever reminder of what I love about the show: its ability to make me laugh my head off, even after watching a man get his head shot clean off.

Of course, between Lee's extremes lies a wealth of complexities that The Lowdown takes great pleasure in unspooling. He loves writing so much that he'll critique the prose in a murdered man's diaries. He adores Francis more than anything but occasionally puts his investigation before her. He's got an ironic Confederate flag tattoo.

All these details add up to create a fascinatingly layered new TV detective, one whose adventures we've only just begun to explore. Here's hoping that viewers can follow in Lee's footsteps and dive further still into the truths at the heart of Lee himself, and of his beloved community in Tulsa.

The Lowdown was reviewed out of its world premiere at the 2025 Toronto International Film Festival. It premieres Sept. 23 at 9 p.m. ET on FX. Episodes stream the next day on Hulu.
