I have been through the entire curriculum and I want to say that it truly depends, for all of the following reasons:

What score are you shooting for? (Personally, I was shooting for a 170+) This is because it is almost necessary that you understand even the most minute details. I've found that if you continuously skip, you will waste more practice questions than usual even if you do eventually go back to catch the concept

How do you learn best? (Again personally, I learn best by watching others do it and then copying them) so I worked most efficiently by watching J.Y.

Lastly, I found that the way J.Y. teaches tends to build on itself. It's easier to understand what his methods are when you understand LR first. But if you already are strong in LR then by all means skip (I wasn't lol).

So to answer your question of does it get better; Personally I was bored at first but as LR got harder I saw the need to watch throughly. But I did skim some videos here and there but it was rare. Do what you believe works best. Just beware of wasting practice questions.
