Nothing has been original for centuries. We just rehash the same old stories and tropes in a way we hope someone finds interesting.
Walt Disney got his stories from the Brother's Grimm fairy tales. The Brothers Grimm just rewote Hans Chriten Anderson. Shakespeare took history lectures and framed them as plays. Most, if not all, fantasies draw off Tolkien is some measure, and Tolkien himself ripped the Poetic Edda, which itself was just a collection of older myths. Goku is based off of Sun Wukong from Journey to the West, Superman was based on Moses. Heck, the Aeneid ripped off the Illiad and the Odyssey, and those stories weren't even original either, just again someone compiling preexisting stories. And the Greek gods at the center of their myths were likely just evolutions of older, Mesopotamian ones.
So I would say no, nothing is truly original. But that doesn't mean it's not good.
