I saw the Nightingale listed as a thriller by the woman who made Babadook and gave it a shot.
The Nightingale: Directed by Jennifer Kent. With Aisling Franciosi, Maya Christie, Baykali Ganambarr, Addison Christie. Set in 1825, Clare, a young Irish convict woman, chases a British officer through the rugged Tasmanian wilderness, bent on revenge for a terrible act of violence he committed...

"Set in 1825, Clare, a young Irish convict woman, chases a British officer through the rugged Tasmanian wilderness, bent on revenge for a terrible act of violence he committed against her family. On the way she enlists the services of an Aboriginal tracker named Billy, who is also marked by trauma from his own violence-filled past."
It's definitely not horror, though the opening is pretty damned horrific. It's a revenge flick. The lead woman is an Irish immigrant who hires an Aborigine to help her track some British soldiers through the wild. She and the Aborigine start off disliking each other, but they bond over their shared hatred of British Tyranny and racism. It's well shot, the wilderness is scenic, and there are there was a nice amount of realistic Irish culture in there so I'm guessing the bits of Aborigine culture were also fair.
But it's also kinda extra with the racism and rape that occurs throughout...I found it gratuitous personally. That stuff helps make hating the bad guys and waiting for their inevitable comeuppance nice, but it's a slow burn loaded with cism, assault, and abuse...the payoff didn't really feel worth the journey to me. I liked Jennifer Kent's work on Babadook and her episode of Cabinet of Curiosities; but this one was a bit disappointing.
If you like revenge films and frontier traveling stuff, it might land for you. But I wasn't feeling it.
