The fictional world building including a basic geography of the worlds/realms (are they each spheres on their own or all part of one big sphere? And the geography of the worlds) and how magic works is underdeveloped, one of the big problems of the show and becoming increasingly frustrating. Way too many plotholes, even of the blackplothole kind (sucking everything in coming a little to close, from other plots, the overall story arc, never to be seen and heard of again, not talking about things which can be explained eventually later). Of course the focus should be on the character development and the story more driven by that, but disregarding a decent world building is harming character driven story telling. Writing the same here what I did on another forum. There has to be a basic structure, rules, a matrix in which the characters have to operate, exposing the conflicts and trouble and drama going on inside a character and between characters. The world has to limit powers and possibilities and consistently so, especially if it is a fantasy magical world. In the end the character are limiting themselves, but the restrains of the world are what brings it to light.
That is why plenty of fantasy worlds fall rather flat if it comes to character development, a few might pay too much attention to detail but most fail in world building, there has to be a logic inside the universe created. It’s not about defining every tiny detail, and one can bend things a bit if need be, but what they’re doing on the show is quite random.
