This review contains spoilers for the first episode of House of the Dragon Season 3.
House of the Dragon Season 3 premiere is a thrilling and in-the-moment arrival of everything this series gets so right. Beginning with the brewing battle between the Blacks and Greens set to spiral into even greater destruction, the episode finds each side forced to deal with grief, betrayals, and unimaginable choices.
Across Dragonstone, King’s Landing and the waters of the Gullet, characters are forced to choose between duty and family, with consequences that will be felt for a very long time. Despite all of its fire, blood and spectacle, this opening episode is far more interested in it’s characters making impossible choices than the war itself.
This episode is more than just a battle-heavy premiere. At the heart of it all, and delivered brilliantly once again by Emma D’Arcy, is Rhaenyra Targaryen. The only individual open to believing that Alicent may have been acting in good faith, Rhaenyra’s trust is also largely responsible for much of the episode’s dramatic tension, most significantly with her son Jacaerys, who is convinced Alicent is trying to lead his mother straight into a trap.
D’Arcy expertly navigates Rhaenyra’s dichotomous existence, a queen in the middle of a war but burdened with the grief and fear of a mother who has already suffered more than most.
What makes D’Arcy’s performance so potent is the frequency with which Rhaenyra is stripped of her agency – time and time again, she sees individuals around her making choices on her behalf in an effort to safeguard her well-being. What good is authority when nobody around you trusts you to wield it?
Harry Collett is equally impressive as Jacaerys. The character has grown significantly over the course of the series, and Collett convincingly portrays a young man stepping into leadership while carrying the immense pressure of being his mother’s heir. What makes Jace so compelling is the lack of any ulterior ambition: What fuels him throughout isn’t selfishness but love and a desire to protect those closest to him. It’s precisely why the episode’s final tragedy lands so hard. Jace doesn’t die chasing glory or power. He dies trying to protect his family, making his death all the more heartbreaking.
Meanwhile, back on the battlefield, Matt Smith looks perfectly comfortable in the Daemon Targaryen armour. With war underway, there’s an obvious urgency to the way that Daemon is operating this time around, but the actor has once again continued to find nuance in a character who could have come off as simplistic, the undercurrent of devotion to Rhaenyra remaining, even throughout all the brutality.
On the Green side, Ewan Mitchell delivers some of his finest work yet as Aemond. What makes the character so terrifying isn’t simply his capacity for violence but his complete certainty in his own judgment. Every scene carries an undercurrent of danger because Aemond genuinely believes he is the smartest person in the room. Mitchell plays that arrogance with chilling precision, making him one of the most unsettling figures in Westeros.
His scenes opposite Olivia Cooke’s Alicent are among the strongest of the episode. Cooke is exceptional here, portraying a woman trapped between guilt, fear and maternal instinct. Alicent understands exactly how dangerous her son has become, yet she is also one of the few people capable of influencing him. Their dynamic is layered with manipulation, desperation and a complicated love.
That complexity reaches an uncomfortable climax in the episode’s most shocking moment, when Aemond kisses his mother after Alicent spends the scene appealing to the vulnerable child she hopes still exists beneath the king. The sequence is deeply unsettling, not because it comes entirely out of nowhere, but because it feels like the culmination of years of blurred boundaries, emotional dependency and power struggles. Both Mitchell and Cooke play the moment perfectly, neither overplaying its shock value nor shying away from just how disturbing it is.
Tom Glynn-Carney also continues his remarkable run as Aegon. Broken physically, emotionally and politically, Aegon has become one of the show’s most tragic figures. Glynn-Carney never asks for sympathy, yet somehow earns it anyway.
One of the episode’s most quietly affecting storylines belongs to Steve Toussaint’s Corlys Velaryon. And after an unbelievable personal loss, it seems Corlys has reconsidered priorities. His scenes with Alyn (Abubakar Salim) are filled with decades of repressed love, resentment, and hurt neither can even define, but Toussaint delivers them with such incredible subtlety.
The Battle of the Gullet does not disappoint; it’s as spectacular as it was expected to be. Huge in scale, dazzling visually, and the action is truly anxiety-inducing. Yet what makes the sequence work isn’t the spectacle itself. It’s the cost. Every single choice made during this episode goes towards what becomes inevitable. Every act of defence, of support or even love, there’s a cost. By the time the battle reaches its devastating conclusion, the emotional fallout feels completely earned.
That’s ultimately what makes this premiere such a triumph. While the battle provides the spectacle, it’s the relationships that provide the heartbreak. The dragons may dominate the skies, but it’s the families being torn apart by war that leave the deepest impact.
As a season premiere, it’s a remarkable achievement. Balancing spectacle, character and tragedy with the confidence of a series that knows exactly why audiences fell in love with this world in the first place.
