if you're care about story that was more about the people--the white saviors with rose tinted glasses--than the cause, probably this worked, almost. And well, Ioan Gruffudd is not that bad of an actor, but sorry, with cast like Michael Gambon, Albert Finney, Toby Jones, Ciaran Hinds and Benedict Cumberbatch, Ioan is the least I want to watch.
I don't know how historically accurate all the details are but the story told matches well with what I remember from my school days. If only we had this to watch back then! If this film falls squarely into a period piece drama in being rather polite and all tea and cucumber sandwiches, I still think it has a useful place in the educational curriculum as well as being a fascinating, enjoyably film to watch.
An absolutely stellar cast, on very fine form indeed, do justice to the history, the faith and the politics of the time. It's fair to say that there are other ways of telling the story of slavery and its abolishment. And truth be told, slavery is not yet defeated. But the road to creating a world in which all are equal has, and will continue to have, mighty landmarks worthy of stopping at and remaking upon.
your view of this will be coloured by one of two things: William Wilberforce as prime mover in the abolition of the slave trade, and costume drama. I care little for the latter, but strongly for the former, and whether young British actors were grandstanding or not, the story of the end of slavery from the perspective of Parliament was told.
It's quite interesting to read reviews of this film from the many campaigners who are very critical of its idolisation of Wilberforce as the great white saviour and the dearth of speaking parts for black actors/recognition of the role black people themselves had in ending the slave trade. It is basically a glossy costume drama which is pleasant enough to watch, but lacks bite.
