Check out this movie called "Worlds Apart" Its in Danish, and subtitled in English, but its about Jehovahs Witnesses. The story is told from the perspective of a girl leaving her overly JW family to go live with her boyfriend, and all the struggles they have.

Its so realistic, it made me cry, and Im a 6'4" 300lb heavily tattooed Harley riding hillbilly gangster with a beard longer than most girls hair.
