Another clunker, I'm afraid, this one seeing such amazing scriptwriting as "Adama looks at the walls and ceiling." What was interesting was Ellen's return - but I'll get to that in a moment.
The underlying theme of the episode is the blending of Cylons and humans, made painfully obvious to us as Cylon work crews work to repair the Galactica (which leads to the aforementioned stare fests from Adama). The Cylon-Cylon pairing of Saul and Caprica 6, which led to a pregnancy, falls apart as they lose the baby. The Cylons are posting pictures of models lost during the war, the same as the humans. It's already started - the Cylons are a part of the fleet.
That was pretty much the important part to this episode. The other part was Ellen's return. Presumably we were supposed to get some more answers like last week's episode, but she instead returned to her previously petty form from before she died. She's apparently the same Ellen as before, but slightly different. As far as answers are concerned, Anders' brain reactivated or something so we'll probably get more next episode.
From what I understand there are only four more episodes to go, so I hope that the fact that Baltar's followers got big guns leads to something fun. Well, fun for the viewers, it'll probably not be so good for those on the Galactica.
Final note for this episode: while it was pretty bad, the scenes after Tigh loses his unborn child are VERY well done and acted. Those scenes were probably the best of the episode.
