Yes it is old; yes the narrator is super intense, and many people were racists in the '60s, but it is a good look at history. The facts of the film are good and it does a good job of overview. I am using it in my classes right now to review the revolution and civil war but also as an exercise in document analysis and Point of View/Bias. It's a good exercise because the bias of the writers is so blatant that it is impossible to miss, and the film was made recently enough that the students can appreciate the goals of the writers. Also, many students have an easier time seeing and hearing POV/Bias than reading it; the nuance is more obvious. Depending on your goals it is good. But I wouldn't leave it for a sub without some very specific work for the students.
