Justin Chang, Variety:
"If '12 Years a Slave' felt like a breakthrough... Parker’s more conventionally told but still searingly impressive debut feature pushes the conversation further still: A biographical drama steeped equally in grace and horror, it builds to a brutal finale that will stir deep emotion and inevitable unease. But the film is perhaps even more accomplished as a theological provocation, one that grapples fearlessly with the intense spiritual convictions that drove Turner to do what he had previously considered unthinkable."
Todd McCarthy, The Hollywood Reporter:
"A labor of love pursued by Parker for seven years, the film vividly captures an assortment of slavery’s brutalities while also underlining the religious underpinnings of Turner’s justifications for his assaults on slaveholders. It’s a film very much in tune with the current state of heightened racial friction and one that will assuredly generate a great deal of media attention, and probably controversy, more for cultural and political, rather than artistic, reasons; creatively, it’s a far cry better than Stanley Kramer, but it’s no 'Son of Saul' either."
Brian Tallerico, RogerEbert.com:
"Most of all, Parker is absolutely phenomenal, portraying Turner as a man whose rage and need for revolution simmered inside him, spurred on not only by what he saw but a Bible that also conveyed the injustice of the world around him. Parker’s take on Turner is more internal than a lot of actors would have gone or a lot of directors would have crafted — he is a man who watches, and the way he uses scripture to convey his increasing rage in the midsection of the film is captivating."
Lanre Bakare, The Guardian:
"[M]ostly, the film is heavy-handed, with subtlety nowhere to be found. The horrors that Turner endures are signposted with soaring music. The focus on Turner is all-encompassing, with other characters, including his wife (Aja Naomi King) and other rebels, feeling thin and unconvincing. When the revolt does come — a rebellion that saw five dozen slave owners and their families killed — Parker doesn’t leave anything to the imagination. Heads are crushed, stoved in and chopped off. Bodies are burned, teeth are broken. It’s a cathartic blood-letting that recalls the huff and puff of "Braveheart," but instead of Mel Gibson splattering the English, it’s Parker hacking at the slave owners."
Sandy Cohen, The Associated Press:
"'The Birth of a Nation' is a beautiful, painful and powerful film that juxtaposes pastoral settings with inhumane violence. Elliot Davis' cinematography captures the ethereal natural settings of the American south and the heartbreaking brutality of slavery... Parker embodies Turner's compassion and heart, on both sides of the camera. As Turner, his eyes communicate a deep understanding of human nature. As the writer, director and producer of the film, he channels that understanding into a moving work of art."

Regardless of the mawkish tone, "Birth of a Nation" lays out the talent of a filmmaker in full control of his material. Among the many impressive images is the shot of a nude Turner opposite his wife, shortly after he rescues her from a vicious auction, their bodies lit only by the candlesticks between them. Much later, Turner's camera roams through hordes of black bodies hanging from trees, set to a moving cover of "Strange Fruit." And the final montage, when Turner's fate merges with an otherworldly vision of the future, bring the drama's full strength to the foreground.
