Love stories where one of the lovers is immortal tend to end in tragedy, or at the very least glum acceptance of one’s sad fate. But Age Of Adaline gives its heroine a happy ending, via circumstances that mirror exactly the events that made her ageless to begin with. Adaline was rendered ageless by a freak car accident that flung her into a lake, where she died from hypothermia, then was revived when a bolt of lightning struck the lake, inciting the aforementioned to-be-discovered scientific phenomenon. In the present day, overwhelmed by the confluence of her love for Ellis and her memories of William, Adaline flees in Ellis’ Saab, only to change her mind and turn around—directly into the front of an oncoming truck, which flings her from the car. She once again dies from hypothermia and is revived by electricity—this time, the EMT’s defibrillator—allowing her to finally tell Ellis the truth of her situation, which he easily accepts. Flash forward to one year later, and Adaline and Ellis are living a happy life together (with a new Cavalier King Charles Spaniel puppy), getting ready to go out on the town—when Adaline discovers a grey hair. The narrator informs us that the process has been reversed, through the very same scientifically dubious yet emotionally credible circumstances that keep Age Of Adaline just barely on balance.
