House of the Dragon Season 3 Review: The Battles Carry It, the Rewrites Hold It Back

House of the Dragon Season 3 earns its 7/10 the loud way. Across eight episodes, from the June 21 premiere to the August finale, the Dance of the Dragons finally becomes an actual war on screen, and when this season commits to that war it is as good as the show has ever been. What keeps it from a higher score is everything between the battles: a middle stretch that idles, and a pattern of adaptation choices that drift from Fire & Blood without earning the distance.

The battles are the argument for the season

The engagement at the Gullet is the season’s centrepiece and one of the best sustained action sequences HBO has produced since Game of Thrones ended. The Triarchy’s assault on the Velaryon fleet has real geography and real cost: Corlys going over the side of his own flagship, Vermax shot down into the sea, and Jacaerys killed under Triarchy arrows. The show lets the losses land rather than rushing past them, and the sacking of High Tide gives the Blacks a defeat with weight instead of a plot beat.

Ryan Condal’s team stages dragon combat with a clarity Season 2 often lacked. Aemond’s descent on Harrenhal and Daemon’s riverlands campaign both play as warfare with consequences, not spectacle for its own sake. If you came to this story for the Dance, Season 3 is where the show finally pays that promise.

Emma D’Arcy owns the season

The performances were never the problem, and they are not the problem here. Emma D’Arcy does their best work in the role to date: Rhaenyra taking King’s Landing, and the throne, is played as triumph curdling into something harder, and the execution of Otto Hightower lands because D’Arcy refuses to make it simple. Tom Glynn-Carney and Ewan Mitchell keep the Green side of the war humanly ugly, and Simon Russell Beale makes a strong impression in limited time at Harrenhal.

Critics broadly agreed the season works; it sits at 91% on Rotten Tomatoes. But the consensus score flattens a real split, because the people who know the book best had a rougher time with it.

Where the adaptation loses the thread

Three kinds of changes grate, and Season 3 commits all of them. The first is rewriting events the book already staged well: Nettles’ patient claiming of Sheepstealer, one of Fire & Blood’s best small stories, is handed to Rhaena instead, and Jason Lannister’s death is reassigned from the book’s named killer to serve Daemon’s campaign.

The second is invented material that costs screen time the real story needed. The secret Alicent and Rhaenyra meetings, complete with a forged letter to Ormund Hightower, soften the war’s central tragedy, which is precisely that these two women can no longer reach each other. The expanded Isle of Faces material, spun out of a single line in the book, is atmospheric but weightless.

The third is altered fates. Sharako Lohar survives the Gullet in the book; here she is rewritten into a revenge arc and killed off. Helaena’s shattering grief becomes serene detachment. Maelor appears to have been written out entirely, despite the show’s own Season 1 family tree. George R.R. Martin’s own public unhappiness with the show’s growing deviations, aired in a quickly deleted blog post, is not a fan invention; it is the author describing the butterfly effect he warned about.

None of these choices sinks an episode on its own. Together they explain why a season this well made keeps feeling slightly off to anyone reading along.

The pacing problem

Season 3 also inherits the franchise’s rhythm issue. Episodes built around a battle move; episodes built around council tables and secret meetings stall, and the stretch between the taking of King’s Landing and the Gullet noticeably marks time. Eight episodes should not contain this much waiting when the source material is a war chronicle.

Verdict

A 7/10 season that contains 9/10 sequences. When House of the Dragon trusts the Dance, with D’Arcy at the centre and dragons actually fighting, it is appointment television. When it trusts its own inventions over the book, it is merely good, and occasionally frustrating. The battles carry it. They should not have to carry quite this much.
