This video is a truly ambitious grand tour of the major subjects in physics hitting on the important concepts. Of course, more time in some areas would help, as for example how Maxwell's equations are derived and interpreted, and a number of other examples, but the video would be too lengthy. But the goal of this video is, I believe, to touch on, what are the cornerstones of physics, and to trigger the start of understanding, and thus to inspire the viewer to pursue the matter in greater depth. And this, the video, accomplishes extremely well. The graphics are very well done towards that end.
