Okay, so I'm not a huge fan of most of the episodes that Michael Angeli wrote. So I was a bit surprised that I liked this episode as much as I did.
Baltar seeing Head Baltar was a stroke of genius, and it helps that James Callis played it so well. I find it interesting that he appears when Baltar is with one of the Final Five. Maybe Tricia didn't want to keep changing wigs.
I find it amusing that the Cavils are ones. It seems to me like they are being overprotective older siblings, so it made perfect sense. Of course, the rampant egotism of the Cavils helps too.
The meeting between the Final Four was odd, especially Tigh. I'm not sure if it was the actor or the directing, but the way he delivered his lines was funny. That said, Tigh is completely regressing back into the Resistance-leader role.
I didn't like how Tory was written in this episode. She's supposed to be strong and aggressive, in counterpoint to Billy, and representative of a harder-edged Roslin. To me, Angeli totally missed the whole point of the character.
It's the same issue I have with Roslin. Yes, Roslin is incredibly anti-Cylon - but she's also not dumb. Like others have said, I don't believe that Roslin would blatantly be so obtuse.
As an aside about these two - I like that Tory is a Cylon. Roslin's aide, be it Billy or Tory, is a representation of who she is and how she acts. Billy was a true human, Roslin was a humanist. Tory was aggresive, Roslin was more hard-edged. Now, Tory is a Cylon and Roslin is acting cold and heartless.
Finally, I know the Cylons are supposed to represent a growing culture. I don't get why Boomer siding to lobotomize the Raiders was such a big deal, or why it swayed the vote. Okay, one specific Number Eight voted to do it - that's an anomaly, not a rule. It's even the model they already tried to box. Gah. It made no sense to me.
