^I liked the movie Riv, but must not remember her extreme attention-to-detail Detective Vision. Maybe since she didn't age she didn't have any normal memory loss related to age?
Note: I mean the memory loss that occurs normally with aging, not memory loss due to a syndrome like dementia or another underlying condition.
That doesn't explain why she has super-duper memory instead though.
EDIT: Didn't realize I was starting a new page; the up arrow is referring to Riv's comment about why Adaline in Age of Adaline had Sherlock Holmes super deductive skills.
I was confused when I was a teen and watched Tim Burton's Planet of the Apes and Fight Club because of both of the endings, but then I realized Burton's PotA remake wasn't really a good movie and didn't care and, in Fight Club's case, I hadn't seen enough movies with the "main character is really the bad guy and said bad guy was all in his head the whole time!" trope yet.
