It's possible Jackie offers some therapeutic value to those of us who never got over that dreadful day. Along with Dec. 7 and Sept. 11, Nov. 22 remains burned into the common memory of three generations. They were days when a bullet, a bomb and a Boeing airliner divided history into eras of before and after. Two of those awful days led directly to wars — lancing, in some ways, our national sense of grief and outrage over them. But Kennedy's senseless death, at the hands of a loner, remains a boil of what-ifs and if-onlys that just won't burst. As they focus on the intimate agony of Jackie Kennedy, Larraín and writer Noah Oppenheim help us, perhaps unwittingly, to resolve the tragedy much as a good therapist would — not by answering questions but by helping us relive the emotions we felt at the time.
