Really good doc and behind the scenes action. music is awesome as you would expect and very interesting to see the band interact with each other. Totally for the super fans though as it is so long. By the 2nd episode though, i had it going on in the background while I was half distracted with other stuff. One item of note though, it did seem curious to me that Yoko was there for the whole doc. It seems like John did not go anywhere without her.
