The Lost Weekend: A Love Story

This is not just another Beatles documentary. It is something in its own category. This is someone’s love story, a very beautiful one.

It is a vivid snapshot of a troubled private life at the apex of the US music scene.

The film, which also details Pang’s Chinese immigrant upbringing and mentions her subsequent life and career in and around the music business, joins other building block documentaries like “The U.S. vs. John Lennon” in performing two services — keeping his memory alive, and wholly charting the many currents of the life of this singular figure in global pop culture history.

“The Lost Weekend” is a compelling movie and a valuable puzzle piece, but it’s only pretending to be the whole puzzle.

Whatever the truth of Ono’s manipulations in this affair — and Pang’s claims, including that Ono asked Pang to look after Lennon in an especially personal way, are at times hair-raising — they tinge this saga with a resentment that’s off-putting.
