As someone who's very familiar with the Nagra audio tapes, it can't be stressed enough how illuminating it is to see all of the non-verbal body language and facial expressions. For example, the notorious scene with George quitting has caused a lot of confusion over the years over exactly what triggered it, because the tape prior to that doesn't indicate a particularly provocative event. On film, with some excellent editing from Jackson, George's silent face tells it all. There's scores of similar instances throughout which add volumes of context. The "Peter Sellers" segment, which has Lennon fried and rambling non-sequiters while everyone chuckles along. On camera, McCartney doesn't look so amused. And of course that soon-to-be classic moment from earlier that day when McCartney quietly recognizes to himself that Lennon is already one foot out the door.
I was initially a little frustrated by the lack of complete performances. The rehearsals were fragmentary enough as it is. But I now feel that the impact of the one true full length performance - the entire rooftop concert - has a lot more impact after 7 hours of this kind of fragmentary build-up. It should be the only complete performance in the film. And having said that, I like that ep.1 includes over the end credits a version of "The Palace of the King of the Birds", a pseudo-classical original instrumental from McCartney, not complete but a coherent edit from an otherwise somewhat shambling recording from Jan. 6. I had hoped to see more recordings like these ("My Imagination", "Commonwealth/White Power", various "Dig It"s) on the Let It Be box, and the version of "Palace" here is well worth adding to one's audio collection.
In all, the suspicions of a whitewash are largely unfounded. I think this is about as accurate as it gets. Probably the most revelatory surprise was the so-called cantina tape, secretly recorded from a hidden mic. This tape, which is about 25 minutes, has been available, but in atrocious fidelity, with sounds of tinkling glasses and forks on plates making it a torture to sit through. Peter Jackson has developed some very impressive frequency extraction software which manages to make these recordings clear and discernable for the first time, and it's probably the best document from the film on the dynamic between John and Paul ("You're the boss", McCartney's demanding arrangements, etc)
