The new HBO series His Dark Materials could fill a hole left by the departing Game of Thrones. Maybe? Possibly?

Here’s the premise: Adapting Philip Pullman’s award-winning trilogy of the same name, which is considered a modern masterpiece of imaginative fiction, the first season follows Lyra (Dafne Keen), a seemingly ordinary but brave young woman from another world. Her search for a kidnapped friend uncovers a sinister plot involving stolen children and becomes a quest to understand a mysterious phenomenon called Dust. As she journeys through the worlds, including our own, Lyra meets Will, a determined and courageous boy. Together, they encounter extraordinary beings and dangerous secrets, with the fate of both the living — and the dead — in their hands. It also stars James McAvoy and Ruth Wilson.
