‘House of the Dragon’ plays a less-addictive game for an earlier throne

HBO has followed the majesty of “Game of Thrones” with what might be called “games of throne” in “House of the Dragon,” a series whose epic visual grandeur belies a smaller and less addictive power struggle, more narrowly focused on the Targaryen line. It’s not bad, and there are dragons aplenty, but it doesn’t produce the sort of characters that defined and elevated its predecessor to prestige-TV royalty.
