Wow. This show may very well have orbited the shark, so-to-speak. Not only did the case fall apart, but it did so in a very predictable and ho-hum manner. It was obvious they weren't going to kill Baltar. It was obvious Lee was going to destroy the case. It was obvious Adama was being convinced by his son. I think they by far made the 'safe' choice in the trial. And WTF, where was the friggin' vice president, who predicted this fiasco? I think he should have been right in the thick of it.
And IF they make Tigh a cylon, then that's it. End of the road. I believe, instead, that it is a form of the Hand of God original episode, where they began to receive transmissions from what might have been earth. I think those 4 just happened to be the 4 who tuned in to it, who managed to hear it, and were in the right place at the right time.
I don't know. The episode was very cool on one hand, but rather disappointing on the other. An enigmatic cap to an absolutely abysmal last half of the third season. This show is in a 'meh' spot for me now.
