"Woman Walks Ahead" constantly teeters on the verge of being an incredible modern western, but for whatever reason, it can just never seem to cross the threshold. And while there's nothing particularly wrong with it, there's nothing otherwise particularly right.
It is cast well, and the performances (especially Micahel Greyeyes) are great. Jessica Chastain's accent seems to waver a bit, but I've heard worse accents in worse movies. It's a little slow, but I was never bored, and there is some beautiful landscape, and gorgeous use of numerous wides throughout that took my breath away.
I just wish there had been a little more exploratory depth to the characters and history. The way they unfold and interact with each other often feels overly simplified for the sake of the film.
