"Beginners and intermediates may enjoy it the most." that's not true,
although I'm not a beginner, this lesson (not a course, it's just a single video) is clearly not for beginners, the problem is that he rushes the basics and do not explain what should be explained for a beginner. And the author video editing skills is not the best, he chopped the video a lot like it was a YouTube video, bruh this is not a YT video for you to do that... So for beginners, I highly recommend starting with Three.js Journey, the real start is there, because Bruno has a lot of experience when it comes to teaching!
