Over a period of eight days, an 18th. century Korean king punishes his only son for attempted regicide. Flashbacks reveal the chain of events that led the son to rebel against his father while the women and courtiers who love them both struggle to deal with the growing conflict.
What works for The Throne is that the movie evinces a common family psychological dynamic that exists between almost all fathers and their sons, but the dynamic is amplified by the fact that the family in question is a royal family and the stakes are higher. As all fathers struggle to challenge and build their sons without breaking them and as all sons endeavor to prove themselves and earn their fathers' seemingly unattainable respect, The Throne shows us how severe that dynamic can be when the fate of an entire country is at stake.
There is something for everyone in The Throne as fathers and sons might learn something about the other side's feelings and motivations while other family members and friends can relate to the helpless frustration of watching their loved ones fight each other.
With all of that psychoanalysis stated, The Throne also delivers exceptionally well for viewers who enjoy lavish costume dramas about royal families and their courtiers and/or period pieces about Asian history and culture. In summary, The Throne is excellent story telling.
