Episode 4, Throne for a Loss, featured a juicy one. Crichton compares the
Honorable mention to his Wile E. Coyote nod. It's not genre, but it's cute. Oddly, these dudes will show up again.
Episode 5 featured no overt Crichton geekisms, though the title itself is a sci-fi nod: Back and Back and Back to the Future. This episode DOES hold the distinction of being the first legitimately good episode of the series.
Farscape: The Complete Series is for sale on Amazon.com. Should you get it? Well, not for this episode, but... better days ahead.
