Sorry to be negative but I gotta say I was disappointed in this film. I had hoped the likes of Martin Scorsese and David Tedeschi, with the backing of Apple and the resources available to them, would have kicked a goal. But they managed to take all the excitement out of the 1964 US moment and make it seem, well, boring.
It was disjointed from a story-telling perspective and jumped around all over the place. Some of the talking heads reminiscences were not only odd in the extreme, some were not even about 1964 (thinking here of Jack Douglas' long, drawn out Liverpool story - it is from December, 1965; and Smokey Robinson misremembering his first meeting with the band, which also could not have been in 1964....)
It all just came out as being a bit flat and uninteresting - which is saying a lot.
Having said that there was some great cleaned-up footage, and the concert material was exceptional. There just should have been more of it.
Seems like a wasted opportunity.
