For those who are too young to remember the real John Winston Ono Lennon -- this film is a good introduction to why he mattered so, why so many people were (and are) devoted to him as an artist and a man, why he was truly the most original voice of his generation.
The film is not perfect -- but in its defense, it covers an extraordinary amount of material and does it well.
Lennon lived 100 lifetimes between 1969 and 1975.
This film concentrates on the biggest conflict he faced at that time: his struggles to remain in the US, and the right-wing paranoia (exemplified by FBI director J Edgar Hoover and Nixon's hatchet man, John Ehrlichman.)
Lennon's sincerity, his naiveté, his charisma shine throughout.
Yoko has been attacked (so what else is new) for being such a strong presence in the film but she was right there beside him. They lived it all together. And she does not use her camera time to diminish him in any way.
Strong recommendation -- primarily because we have to remind ourselves that there are times to speak up and times to act.
John Lennon: we miss you so.
