For what this movie signifies, it's very important and great on what it's representing, but the movie as a whole is pretty okay. It lacks the budget it needs to be great, but at the same time I give it a 7 because the two main leads save the film and are quite frankly, phenomenal.
Those two main leads being William Hurt and Chiwetel Ejiofor. They give two powerhouse performances and pretty much save the movie from being a 5 and they're chemistry is real and pure as to when the final result comes at the end, it is touching to the viewer because of how great these two performances were as well as it's touching from the historical aspect of it too. Overall a pretty good movie.
