Here's what we learned about the series on Saturday, as the cast and creators revealed an extended trailer at Comic-Con San Diego - so you can judge for yourself.
It's a family affair (not unlike Jaime and Cersei…)
House Of The Dragon is set 200 years before Game Of Thrones, and follows the fortunes of the Targaryens - a noble family with the power to control dragons.
It's based on George RR Martin's 2018 novel Fire Blood, in which the Targaryens unleash the worst imaginable family row - a gruesome civil war.
King Viserys (Paddy Considine) sits on the Iron Throne, the most dangerous chair in Westeros, as Lord of the Seven Kingdoms. And the succession is proving competitive.
"I will not be made to choose between my brother and my daughter!" he rages in the extended trailer for the series. As Viserys is described as a decent man, a good king who believes in duty, the brutal forces of Westeros will likely contrive to crush that goal like Gregor Clegane crushes skulls. (No spoilers…)
The Stark and Lannister families, who dominated GoT, will appear mostly as bit players.
We meet the Targaryens at the pinnacle of their power and wealth. Oh, and they've got 17 dragons and they ride them.
The dragons are coming
GoT fans will recall what Daenerys Targaryen (a descendant of these characters, played by Emilia Clarke) managed to achieve with three dragons. That makes 17 an intriguing prospect - and a potentially devastating weapon.
"It was important to differentiate the way they behaved and acted and bonded with their riders," Condal told the audience at Comic-Con's highest-profile venue, Hall H.
"George [RR Martin] specified their colour and size and age", and the rest was fleshed out from there.
For example, Caraxes - whose riders include Prince Daemon Targaryen, played by Doctor Who alumnus Matt Smith, is dubbed the Blood Wyrm due to his cantankerous nature and general ferocity.
"We've designed dragons that you won't even see in Season one," promises Condal.
Describing what it's like to film the dragon riding, Milly Alcock - who plays young Rhaenyra Targaryen, mused: "You're propped up on what looks like a mechanical bull that you might ride in a bar or pub, and it lifts up six feet in the air and there are four guys with leaf blowers.
Good and evil? Well, nobody's perfect
Panel host and podcaster Jason Concepcion asked Martin what the ideal ruler of Westeros would be like.
"Someone who regards being king as a duty rather than something they are entitled to," he replied. "… And cares about building roads and sanitation in Kings Landing!"
