The Battlestar Galactica seems to have found Earth, Terra, the 13th tribe -- but what they find is altogether dissatisfying. This episode fails to play up the possible differences between two branches of the human race, 3,000 years removed. Instead, we are given a glimpse of humans who speak the same language, arrange themselves in similar social patterns, and only diverge in that they're used to a different atmosphere than our own (but then again, this is only Lunar 7, and not Terra itself).
As villains, the Eastern Alliance is perhaps as befuddled, as cariacatured, and as easily outsmarted as the Cylon Empire, except that they have smaller and slower ships to boot. The revelations about Terra are decidedly small, and the threat posed by a single fighter pilot is pretty flimsy compared to the threat of a Cylon battlestar.
The characters have weak motivations -- the Morlands change their minds very quickly, the search for records on Paradeen is abandoned once they're captured the Eastern Alliance soldiers, Sara is destroying ships to keep Apollo on the planet surface one hour and saying to Michael "our children" the next. The androids Vector and Hector may remain an interesting example of camp, but there is nothing particularly striking about any of the new developments this episode has to offer.
If "jumping the shark" seems a bit harsh, I have simply to say that this episode bears ill tidings of things to come.
