Kingsman: The Golden Circle is something of an anomaly for Matthew Vaughn, a filmmaker who is notoriously selective about which projects he undertakes.
Not only was the subversive spy follow-up the only sequel he's ever helmed, it was also the first time he's stayed within the same genre for two movies running.
Granted, X-Men, Kick-Ass and Kingsman are all comic book adaptations, but very different ones spanning three different categories. One is straight-up superhero fare, the other a parody of that concept, and the latter has more in common with the outlandish James Bond movies than the world of capes and spandex.
Although Vaughn's relatively small back catalogue already spans a diverse range of genres, common threads run through all of his movies. They're always fast-paced, laden with edgy humour and offer a twist on their subject matter's established norms.
In short, Vaughn has built up a reputation for putting his own stamp on genres and making action movies for the more discerning cinemagoers.
He may have dropped out of more films than he's actually made, but that's resulted only in a body of work where quality reigns supreme over quantity.
