Or does it stray from the consensus in ways that are outdated or controversial, and it's best to avoid it if one doesn't already have some familiarity with the subject?
Of course, I don't expect someone to go comb through 20 hours of classes to give me an answer, but I'm interested to know if someone is familiar with professor Freedman and his work, and how it's viewed by other scholars of the Early Middle Ages.

Professor Freedman is a distinguished scholar of medieval Spain, though I'm unable to comment further on his credentials. At the risk of making an appeal to authority, generally a tenured professor at a good school with multiple monographs to his credit is going to be at least competent in his field. There may be some minor areas where he strays from the consensus, but that's not necessarily bad. I would give it a try. At the very least, it's bound to be far better than you'd get out of a documentary or a pop history book and will provide you a good introduction to the topic.
