I finally finished it yesterday. It was interesting from a songwriter's and musician's perspective to see how they worked together and realize that in some ways my process is a bit similar; that stuff Paul was doing to come up with Get Back is a lot like how I play around with chords and melodies in my studio in order to get to something worth keeping. Words flow afterwards. Gosh, it'd be fun to have a collaborator I could write with like that.
But I'm no Paul, that's for sure. Nobody but Paul is Paul. What struck me most was that everyone had a whole lot of general ability; the scenes where they were trying to sort out who was going to do what because someone wasn't on their usual instrument, George struggling with the piano and finally giving it all up to Billy, and I also feel completely vindicated for drinking wine at rehearsals now

They're also pretty casual about how they sound for the most part, right up to where they're tightening it all up for the recording and show.
In Part 1 I was a little miffed at George for being a bit of a downer and he seemed a bit... how should I put this? Slow on the uptake? I thought it might be hard to be around him. But after a period of time I saw that he was just emotionally checked out and tired of the John and Paul playroom; he wanted to get on with it and had a whole lot of music simmering in there with no place to go.
As for who broke up the Beatles, seems to me it was Allen Klein; all the significant others were a presence from time to time, Yoko was there because John wanted her there, she seemed pretty quiet unless she was invited to join in on their goofing around, and it was nice seeing how they all interacted with Heather.
But the thing as a whole was a bit of a slog, and we all knew how it ended. I ended up fast forwarding through much of the music in part 3; I can only hear "Get Back" so many times. By the time we got to the rooftop I was pretty over it.
It did make me want to read a little more about each of them individually. It's clear that certain things were glossed over; John seems pretty functional for a junkie. I've read some of the biographical stuff but I'd like to read more. I was never a huge Beatles fan back in the day and have grown to appreciate them as an adult.
