I could try to explain this episode to you, but I’m not really sure I understood it myself. I think somewhere in there is the moral that it is important to sacrifice your life for complete strangers if you want your planet to survive a horrible supernova that will kill billions of strangers on other planets. Or something. This is the cheapest looking set I’ve yet seen on Trek. It’s, like, Dr. Who-looking cheap. Also: actual theremin on the soundtrack. WTF?
