I think this is one of two great and popular series right now that are essentially tributes to Star Wars, scifi comics, action, bots, with great characters and emotional connections. (Saga is the other one; maybe you’ve heard of it?). Both are great in their own ways. Volume three of Descender was slower, more reflective, more emotional. Volume 4 is again more action-driven. Tim-21, Telsa and Quon escape the Machine. There’s a scary Tim-22. Andy and Effie conflicts. Driller and his new friend Mizerd.
Lemire and Nguyen have a great series here, with a complex scifi story and gorgeous watercolor art. Just lovely to look at. But think of it: Royal City, Black Hammer, Roughneck, Descender, all excellent, all advancing this year, a career year for Lemire. One of the three or four or five best comics guys in the world right now, for my money.
