This is the most outstanding tv miniseries I have ever seen. I saw it in the late 1970s. It prompted me to read into the subject and I found everything was scrupulously accurate history. The Parliamentary speeches were virtually accurate word for word, as was the legal judgment in the Somerset Case and incidents like the Zong, where the captain jettisoned his slave cargo to collect insurance money. The slave catching raids in Africa and the brutal middle passage to the Caribbean did not hold back. It is far, far superior to the dumbed down film Amazing Grace and to the typically low brow network Roots whc was broadcast about the same time.
