There is a selection of books that I have read a couple dozen times, then I got the audiobook versions. Some books make no sense until you reread them and finally notice the clues that were left behind on the very first pages.

It's like with any other medium, the first run through is for entertainment. For example I watched a veritasium video about quantum physics. Fascinating. But I couldn't explain anything because I didn't understand it. It takes several watch to actually understand the concepts.
