There Has to Be a Twist in M. Night Shyamalan's Old, Right? Here Are 4 Theories

According to Twitter user @randehman, the beach in Old might have some sort of device or curse that consistently creates aging clones that the original family members find. Eventually, everyone in the original family dies, but they're replaced by confused older clones, who, in turn, get replaced by older clones until everyone ultimately dies out. Is this theory a little convoluted? Sure. We have to admit it kind of makes perfect sense for a Shyamalan twist, though!
