I remember when this show came out in the mid to later 90's. It was a terrific series on FOX. It was just like the X-Files, but a tad bit better. I just watched Glyphic, and was amazed by this episode. When I read the review I thought it would be like an outbreak of a particular virus, but it had a different meaning altogether. The cast was excellent; and the plot gave the viewer something to think about.The reason why this series was popular was it out there in some episodes;and it did make you think in other episodes,especially this one. It did have an extraterrestrial meaning; and to some would be a turn off, but to me it makes you think. What would we do if we had extraterrestrial knowledge to help cure loved ones; and others from an illness/disease, would we use it? Kris L. CocKayne
