The King’s Man isn't an offensive film, unless you find being unremarkable objectionable—in which case, co-writer/director Matthew Vaughn might be due for some complaints. It runs quite long, but despite that, it seems unable or unwilling to make room for even a little bit of sense. Think about this: British nationals travel to Moscow with the goal of eliminating Rasputin, who they see as a harmful influence on the Tsar—and he is, nevertheless, Rasputin remains the Tsar’s most valued and dependable advisor. It's hard to imagine the Russian ruler would be happy continuing an alliance with England if he learned that some English spies had just murdered his closest confidant in a brutal fashion. Luckily, he never discovers this—or at least doesn’t seem to; the sequence where the British attempt to conceal the murder and stage it as an accident is simply missing, likely because it was never composed or filmed. That said, I did enjoy Rasputin's death scene, which incorporates all sorts of stories about his supposed demise (to be precise, the myth surrounding it created by Prince Felix Yusupov); poison, beatings, gunshot wounds, and drowning in icy water. This isn’t a spoiler; first because it occurs roughly halfway through the movie (and when I say “halfway,” that means there's still a considerable amount of time left), and second because his famous death is so widely known that it even has a trope associated with it. What else wouldn’t be considered a spoiler? The identity of the criminal mastermind behind the nameless organization—I would call them OWCA (Organization Without a Cool Acronym), if that name weren't already in use—who intends to cause chaos worldwide; an identity I won’t disclose because it should be obvious to anyone familiar with the Law of Economy of Characters (where a seemingly insignificant character turns out to be far more essential to the story than initially suggested. I will just say that this villain’s unbelievable ability to instantly appear in distant locations, facilitated by nothing more than the demands of the screenplay, creates a plot hole so large a submarine could pass through it—and literally does.
