'House of the Dragon'
If you thought the best thing about "Game of Thrones" was its brutal violence, you'll be thrilled with the blockbuster's first spinoff. Set more than 180 years before the Emmy-winning series, the story revolves around a Targaryen civil war, triggered by the resistance to a woman ascending to the Iron Throne. For every magnificently shot battle, there are three scenes only interested in grossing you out (don't plan on visiting the beach after meeting the flesh-eating crabs). Early episodes could use some comic relief. An appearance by Peter Dinklage's Tyrion makes no logical sense, but if we're going to believe in dragons, why not a time machine, as well? 9 p.m. ET Sunday, HBO
