Within the niche of speculative fiction in TV shows, it's not uncommon for fantasy and science fiction to get lumped together. While they do focus on realities that differ from our own, there are many elements that differentiate the two, like the focus on magic versus hard science and technology. However, this is what makes it even more interesting when writers and showrunners discover the ways that the genres can go hand-in-hand. Since they both touch upon the hidden realities of the unknown world, the limits of a science-fantasy series are endless.
