The line between science fiction and fantasy gets pretty wobbly—where do you stick Star Wars?—but some things just straddle it with pure glee. Earlier today, we were debating about shows that are both science fiction and fantasy. But what’s the absolute best blend of the two, of all time?

Please include a picture, poster, clip, comics panel or other visual representation of your chosen series. And please mention the name, why it’s both fantasy and science fiction, and why it’s excellent. Thanks!
