This is mostly just music. No explanation of what they're doing/trying to do and no appearances by the director or even Glyn Johns.
The only infighting is a shorter version of the Paul/George scene extended in "Get Back," but this time George isn't even shown leaving the band! Maybe that's all the fighting there was? Pretty harmonious, imo.
I *think* the only stuff in this one not in the new one are the sloppy versions of "You Really Got a Hold On Me" and "Kansas City," which are cute enough, but messy as all get-out.
The one advantage here is they show the full versions of "Let It Be," "The Long and Winding Road" and "Two of Us" from the studio (which would've been nice in the new one, since it would show they worked 'em out all the way), and there's more footage of the rooftop concert and minimal dialogue with passersbys/the cops.
There's almost no "Abbey Road" stuff, though, besides the same "Octopus's Garden" bit.
This wasn't as bad as I'd heard, tbh.
