The concept of “family” in the Fast and Furious series is one of the best things about the series – if not the best thing. Dominic Toretto views family the way that fandom and fantasy heroes view family. He collects people who are deeply loyal to him and go along with his wild ideas, even though they can confront him and call him out at times. It doesn’t hurt that half of the members of la familia are people who Dom has had some kind of antagonistic relationship with at first… starting from day one with Brian O’Conner (literally) being on his case in the first film before becoming an integral part of his life.
