Matthew Vaughn’s Kingsman films are reimaginations of the spy genre which have become very successful. The movies follow Colin Firth’s Harry Hart, a top British spy, as he trains Taron Egerton’s character, Eggsy, to be his successor. Eggsy goes from an unpolished youth to a refined covert killing machine. However, all good things must come to an end. The final film in the franchise is nearly done, as Vaughn has already figured out the beginning and the end. Now, the director just has to figure out the in-between.
