It's difficult to watch The Woman King and not conclude it's a masterfully made movie. It has soaring action scenes—the sort that will make you squirm and scream—unconventionally led by a cast of female Amazonian warriors. It has Viola Davis, whose reputation as one of the most formidable actresses alive needs little explanation. And it has a riveting, relevant plot, centered around a kingdom in West Africa that begrudgingly participates in the 19th-century slave trade while it makes moves behind the scenes to hamstring it.
