Given that I watched this in IMAX, the only real “fault” to this was the occasional shakiness/abruptness with the camerawork.
Everything else - while on the surface it’s “just a concert”, the significance of the event, the performers and history aside Peter Jackson and the production crew did a superb job in capturing a candid picture of not only the Beatles but also those in the periphery. The “subplot” of the young policeman, was an unexpected bridge between myself as a viewer and the reality of the moment.
