On one hand it omits a huge amount of detail out of necessity, you can’t fit that much into 20 minutes. But it does manage to convey an incredible amount of information in the time it has.
It manages to convey the broad strokes and important concepts, and helps the viewer put their existing knowledge into context and better understand how it fits into history. As an example, people know about the Israeli/Palestinian conflict. But most people probably only really know that there are two sides that have been fighting for a long time, and many think this has been going on ‘forever’. But now they know the history leading up to it.
The history classes I’ve taken were actually pretty great. Specifically they did a good job going into depth and developing an understanding of certain time periods and connecting that history to the present. But I feel that this sort of broad overview (the entire timeline, so to speak) is also valuable, and it’s something that my history education lacked.
PS. I wish he expanded on racism and the creation of the concept of race. He does go into it a little bit when he talks about Hitler but it fails to convey where that idea came from and makes it seems like this is just some weird quirk of Hitler. I feel a few seconds talking about people coming up with these ideas would have been really great.
