House of the Dragon continues to perform strongly on HBO Max weeks after its third season finale, ranking third among the streamer's Top 10 TV shows worldwide even as its fourth and final season remains in development. The Game of Thrones prequel's sustained popularity underlines HBO's ongoing reliance on the franchise, with reviewers and audiences responding especially well to the latest run of episodes. The show follows the Targaryen succession dispute between Rhaenyra and Aegon II, known as the Dance of the Dragons, with season three depicting Rhaenyra's difficult rule after taking the Iron Throne.

Season three episodes have earned IMDb scores between 7.5 and 9.5, alongside a 91% Certified Fresh rating from critics on Rotten Tomatoes, though audience approval sits lower at 65%. Beyond the current run, HBO has confirmed a fourth and final season of House of the Dragon for 2028, a second season of the spin-off A Knight of the Seven Kingdoms for 2027, and a feature film titled Aegon's Conquest, set 300 years before the original series and linked to writer Beau Willimon, though casting and a release date have not yet been announced.
