In fantasy and sci-fi especially, where worlds are often magical and strange, and the rules are different, the very first scene can matter more than ever. Here are eight of the best opening scenes in fantasy and sci-fi TV. It was terrifying and cinematic in a way TV hadn’t really done before. CR: Patrick Brown/FXAlien: Earth is newer than everything else on this list, but its opening nailed the tone right away. Even if the sci-fi aspect wasn’t there, that opener would still work as a fascinating Western TV show.
