I loved the doc, my slight disappointment is that this was a relatively conventional period, compared to the couple of years before. No insight into how you end up with brilliant, sonically outlandish stuff like Strawberry Fields, Tomorrow Never Knows, I am the Walrus etc. Of course there's masses of stuff written and spoken about those things too, but not the incredible fly-on-the-wall view you get in Get Back. Maybe it's for the best.
