I recommend studying it. It is such a fine piece of work. Sure they may be some errors here or there. Also, if you are not a fan of Sitchen then part 3 may put you off. If you know about the Saturn/Cube worship though, then you'll probably pick it right up.

I've watched this at least 6 times in its entirety and pick up lots of things I missed, each time.

I am glad people are sharing this again.
I highly recommend his other works as well that are still on his channel (at the rate youtube is going it may not be up long though).
