The plot of "Exodus from Genesis", Farscape's third (or second, if you look at the episodes by air date) episode is nothing unusual: Moya gets invested with bugs. What makes "Exodus from Genesis" succeed is simply that everything works. The character interaction, acting, special effects, and visuals are all at least adequate. This episode is a good step above the previous "I, E.T.".
"Exodus from Genesis" opens with a Peacekeeper Marauder scanning around for Moya. Some strange particles floating in space block the scan, saving Moya. The Marauder leaves, but the particles turn out to be a collection of bugs, which then infest Moya. I can't help but wondering as to how the bugs managed to survive in open space, but that's not a major issue. The bugs soon raise the temperature and take samples of the crewmembers' DNA. The temperature increase is particularly harmful to Aeryn, who, as a Sebacean, is subject to heat delirium. The bugs seal off an area of Moya and start to produce clones of the crewmembers.
The efforts by John, Zhaan, D'Argo, Rygel and Aeryn to stop the bugs from killing Aeryn and investing the ship are handled with full competence by director Brian Henson. Each character is well-utilized, and the climax, involving the return of the Marauder, is handled intelligently. There is a slight continuity problem in that Crichton's plan at the end, aimed at convincing Crais that he can replicate himself, is never mentioned again. Also, the soundtrack and atmosphere still feel kind of experimental, which is nothing serious considering how early this episode is in the series. Overall, "Exodus from Genesis" is a perfectly good Farscape episode. Sure, it doesn't go above and beyond, but it has all the action, drama, and character development that makes Farscape so great. 3/4
