Nothing about Matthew Vaughn's prequel to 2014's 'Kingsman: The Secret Service' and 2017's 'Kingsman: The Golden Circle,' 'The King's Man,' is particularly good... except that it ends. Gone are the over-the-top violence, exciting villains, and great spy gadgets that made the first two movies so entertaining. Vaughn seems to have trouble deciding what kind of story he wants to tell, creating a confusing, convoluted, and overly lengthy story that seems to break into different movies as the movie goes on. A truly unnecessary prequel.
