House of the Dragon season 3 review: Targaryen civil war erupts in full force

House of the Dragon season 3 review highlights major battles, dragons and Targaryen civil war escalation

House of the Dragon season 3 intensifies the Targaryen civil war as the long-anticipated conflict between Team Green and Team Black erupts across land, sea and sky, according to early episode reviews.

The third season of the Game of Thrones prequel, streaming on HBO Max, Sky Atlantic and NOW TV, picks up after a two-year build-up and quickly accelerates into large-scale battles and political chaos. Early episodes focus on high-stakes confrontations, including naval warfare and major dragon sequences that significantly raise the scale of the series.

Showrunner Ryan Condal pushes the narrative into faster-paced territory, moving away from the slower political groundwork of earlier seasons. The season reportedly opens with immediate conflict following the events of Season 2, delivering a more action-driven structure while maintaining the show’s political core.

Emma D’Arcy returns as Queen Rhaenyra Targaryen, with Olivia Cooke as Alicent Hightower and Matt Smith as Prince Daemon Targaryen continuing to anchor the central power struggle. Their storylines remain central to the conflict between the rival factions vying for control of the Iron Throne.

New cast additions also add fresh dynamics to the ongoing war, including James Norton as Lord Ormund Hightower, whose shifting loyalties and political influence add further unpredictability to the Green faction’s strategy.

Despite the faster pacing and increased spectacle, the series continues to balance its large-scale battles with character-driven drama and political tension. Themes of power, legacy and gendered rule remain central as the war between the Targaryen factions deepens.

The season has also been praised for its visual effects, particularly its dragon CGI, which plays a key role in escalating the scale of conflict across Westeros. With the war now fully underway, Season 3 positions House of the Dragon as a full-scale political and fantasy war drama.
