Tuck Everlasting (2002) on Netflix

Tuck Everlasting is the story of a girl named Winnie and a family whom she meets, the Tucks. The Tucks have a secret, they're immortal. They drank water from a spring that was actually a fountain of youth. Until the end of time, they will stay that way. Winnie falls in love with one of the Tucks, Jesse, a "17"-year-old boy who shares the same feelings for her. She is then kidnapped by Jesse's elder brother. Meanwhile a suspicious man in a yellow suit befriends Winnie's family over time while Winnie is gone. He spies on the Tucks and it is learned that the man in the yellow suit desires the spring so that he can sell waters to the citizens for profit. Jesse's mother violently bats the man with the yellow suit; with the rear end of a rifle. The hit is so massive that the man dies instantly; constables manage to see the attack and arrest Jesse's mother for killing the man in the yellow suit. Winnie helps break the Tucks out of jail and takes their place in the jail cell. The Tucks decide to leave the area and invite Winnie to join them. Winnie is forced to decide whether to drink from the spring and live forever, or live a mortal existence. She decides to stay behind. After many years, Jesse returns to the tree where the spring used to be, and it is revealed that Winnie chose to never drink from the spring. It shows that you should not fear death, but to fear an unlived life. You don't have to live forever, you just have to live.
