I'm also anti hyphen. On the bright side, I think the word "sci-fi" is the rare instance that it works though. Additionally, there is some trademark love for the sci-fi string. And science fiction is a huge market.
I think this would be a tough sell in the long run but who knows anymore. It's not worthless, it's just not going to be an easy sell. You could list it 1000-2000 BIN and see what happens. If there is no traffic and no offers over the next year or two, drop it. But if you get some traffic and low balls, hold on for sure
