Not bad! The narrative of the documentary itself is nothing groundbreaking, and the clips and photos are basically just a retread of material from Anthology and elsewhere (and yes, the performance clips feel very short, though that's probably for legal reasons). But almost all of the contributors have interesting insights, either into the personal history of Lennon and McCartney (Miles, Cleave, and Voormann) or from a musicological perspective. Particularly enjoyed Ingham's comparison of the different takes on blues in "Hard Day's Night" versus "Can't Buy Me Love." (Apparently he wrote a Rough Guide for them as well, interested to see if he does similar analyses there.) The only sour note (heh) is from Christgau, whose only critical opinion seems to consist of repeating "Paul was a hack, John was a genius. I like John better" for each song. (Though it's funny to watch his hot takes be refuted by all the other talking heads, who are actually giving insightful commentary.)
