Yale's introductory Greek history class with lectures from Donald Kagan is available online and part of it covers the Mycenaean empire and its fall.
+1 for this.
For those that are interested:
It gave me a lot of perspective on how much activity was happening all over the Mediterranean and beyond at that time. This and related channels have a lot of long form content on Ancient History, which I really appreciate.
edit: harari is a hack, you wouldn't have made the comparison had you read the graeber/wengrow
edit: for the record, answering in edits is weird and I'm against it... authors slinging mud is hardly a case for their own competence, besides recommending a book about the whole of history to someone who wanted documentary recommendations on a very specific topic in History is also a bit of a hack
