There exists some fantastical worlds that are so meticulously built—and so emotionally loaded—that a single watch can only scratch the surface of an ocean-deep fantasy TV series. Quite a few shows hidden in the vast genre not only reward rewatches with loads of hidden clues and deeper character understanding, but also with the excitement of knowing where the enchanting fantasy will guide its viewers. Moments of romance, incredible costumes, and iconic lines are sometimes so good that a rewatch is simply inevitable—and adds to the magic of the series.
