Collider has published a ranked list of ten fantasy television series praised for exceptional worldbuilding, the craft of establishing a fictional universe's geography, politics and culture in a way that feels immersive rather than overwhelming. The feature argues that strong worldbuilding is central to fantasy storytelling, since many of these shows are set in worlds entirely separate from our own, and highlights series that have succeeded in making their settings feel lively and coherent.

Among the entries discussed are Star Wars: The Clone Wars (2008–2020), praised as canon-establishing and for expanding the galaxy with new planets, cultures and lore; Attack on Titan (2013–2023), noted for its dystopian walled society and deeply detailed lore around titans and human defences; and The Dark Crystal: Age of Resistance (2019), included for its richly realised fantasy setting. The full list ranks ten shows in total, though the provided text covers only the top three entries in detail.
