Perhaps the most lowbrow historical drama I've seen in recent years, this occasionally amusing historical fiction is marred by all characters essentially involving themselves in deadly court intrigue while having the intelligence and substance of the contestants on Temptation Island.
It finds itself a showcase of Elle Fanning in her finest role you date as the lead role, which unfortunately mostly displays her own limitations and that of the writers. Instead the spotlight is routinely stolen by the nominal antagonist, her husband the emperor, gleefully played as a complete buffoon by Nicholas Hoult. The show is at his best when he is portraying a portrait of a spoiled, childish emperor - despite being the largely idiotic villain whose only that lies in his casual cruelty, the actor manages to portrays a deep emotional role of a cruel man whose unrivaled power from a young age has rendered him impotent in intellect and leadership. But it is often said that a great hero requires a great villain - The Great has neither.
It is tragic that schoolyard intrigue outshines the machinations by writers who can only write supposedly intelligent characters by making the rest of the world moronic. They clearly decided to discard any element of historicity early on, no doubt fearing it would bore the audience. This isn't a wrong choice by itself, as being unshackled by history allows the writers to spread their wings.
And yet. What is instead managed is losing the fascination and grounding of actual history and replacing it with by vapid melodrama that lacks both depth and nuance.
Best watched as a drinking game where you joyously shout huzzah! Along with characters, where company copiously imbibing will allow you to forget that you're watching reality television turned into costume drama. There is enjoyment to be had here, but of the sort that you might imagine if Game of Thrones had only had the last season and you approach it as completely free from history, intelligence, or even the lowest sort of cunning.
