This episode wins a lot of points for being just so way out there. There’s a lot of talk about consciousness transference and mind expansion. It’s some heavy far out stuff for prime time TV of its day (no wonder the show was axed next season.) Also: a great monologue where Kirk explains why the Enterprise – nay! mankind! – must take risks. He concludes: “Risk. Risk is our business. That’s what this starship is all about. That’s why we’re aboard her.” I’m not kidding around, it is a rousing and moving speech. Also: when they are possessed by the SuperSphereLamps (if you’ve seen this, you know what I mean) their voices echo. How cool is that?!
