6 Underground isn’t subtle about its themes. It’s not that kind of a movie. At the end of the day, 6 Underground is all about the healing power of family — both the one that you’re born with, and also the one that you choose for yourself.
When 6 Underground begins, One is convinced that the best way to run his renegade military operation is to minimize all emotional ties. The Ghosts only refer to each other by number, and don’t know their partners’ real names. They only operate in cities they’ve never been to before, and can only interact with people they’ve never met. When Six dies in the film’s opening mission, Two suggests that the group is his only family. “We’re not a family,” One scoffs. “Not the Cleavers.”
But you can’t have a group of people operating in close proximity like that, especially not in life-or-death situations, without building bonds. Over the course of 6 Underground, the Ghosts grow closer. Against One’s wishes, they share their real names. While freeing Murat, Four gets cut off from the group. One tells the Ghosts to leave Four behind, but they defy his orders and rescue their comrade.
Ultimately, it’s not a bad thing. The closer the Ghosts get, the better they work together, the more successful they become, and the happier they are. By the end of the movie, they’re a family — a dysfunctional one, sure, but a family just the same.
