I mean I wasn't around in the 18th century to confirm firsthand, and even calling me an amateur historian would be generous, but the French trappers seemed pretty on brand, compared to other books and movies I've seen them represented in. Weren't any other white folks in the movie.
There's probably some "patriarchy bucking" in the movie, but it's mostly a young girl who's apparently an orphan, that would rather hunt game than forage and make medicine with her grandmother, while dealing with other young men that are kind of dicks, while her brother tries to advise her how best to deal with the situation.
I don't know if you caught this part but there's also a Predator in the movie killing everybody.
