Nice romance, well acted, but I found a few froubling flaws.
Adaline gets married, has a daughter three years later, and loses her husband four or maybe five years after that. Were she and her husband trying not to have children except that one? Fast forward to Adalline's daughter as an old woman. She's had a wonderful life, so Adaline says and her daughter, Flemming, acknowledges. Flemming has had romances, but as far as we know she has never married or had children of her own. Finally Adaline stops running and settles down with the third love of her life, at the age of 107, but she is really only 29. We see Adaline a year later, she looks beautiful, but she's still slender and definitely not pregnant. She's ready to grow old with her new love, but there is no mention of having children. Is he going to sacrifice the wonder of having and raising children of his own? There is a lot of "I love you," and "I want to grow old with you." but no "I want to have a family with you." at all. It's painful by the way that it is avoided.
I think it would have been fun if an 84 year old Flemming couldn't go to the New Years Eve party, because she had to babysit her new baby brother.
Adaline's maiden name in Adaline Bowman. When a policeman stops her at age 45, although she is a widow with a young adult daughter, she is still using her maiden name. Similarly when she goes to England, she is still using her maiden name. During most of the period, women took their husband's last name at marriage and kept it. It is only very recently that some women have chosen to keep their birth or maiden names.
Finally, there's something a little weird about having a big romance with a guy, and then going off to marry his son with father, and son and daughter by a previous marriage all in the know and approving.
Oh yes, when Adaline had her first automobile accident, it was 1937, and women very rarely drove cars.
