Portman gets it right, portraying Jackie Kennedy.

Rating: Null/10 (30 May 2017)

My wife and I watched this at home on DVD from our public library.
Maybe it was different in the theater, but on the DVD the sound mix is annoying, the musical score is often ponderous and way too loud, detracting quite seriously from enjoyment of the movie.
Regarding the actual story, I remember Jackie Kennedy quite well, I was a freshman in college when JFK was murdered, and I remember the later years when Jackie married Aristotle Onassis, everyone assumed because he was wealthy. So watching any movie of Jackie, for me, is a pale imitation of having lived through it.
Still, Natalie Portman is credible as Jackie Kennedy, who was only 31 when she became First Lady, and only 34 when the events of 1963 occurred, pretty close to the actual age of Portman. I don't recall it seeming so young back then but today it seems very young.
When you listen closely to Jackie Kennedy you hear a slight speech impediment, a trait her daughter Caroline inherited. Portman clearly spent lots of time studying and practicing because she pretty much gets it right.
This movie focuses almost entirely on the events right before, during, and right after JFK's murder in the streets of Dallas, showing how Jackie reacted to what was going on, what demands she made, how she (and others) compared their almost 3 years as President and First Lady to "Camelot."
The storytelling technique is to use a fictional journalist, played by Billy Crudup, doing an in depth interview of Jackie in her residence after leaving the White House. For those who have grown up in more modern times this is a good movie to give a glimpse of this complex and often mysterious former First Lady.
