Yeah, I don't know how to convert people in rl. I only ever try on people who already like Classic Who online. Because your target audience is the one you can tell it's going to be slow to start (but skip to Seek Locate Destroy if needs be, because it does drag till then) and to imagine any Terry Nation serial (shot in a quarry) meeting Robots of Death, with bonus Robert Holmes and reused props.

Crackiest moment is definitely most things, though. Yes.
