Tragically, it’s the season finale of Battlestar Galactica tonight, unquestionably one of the best shows on television in years. There are only two hours left of the four season series, and I wanted to take a look back at some of the shows best moments before it ends. Enjoy the list (which is in chronological order), and be sure to share your favorite BSG memories as well.1) Earth ExistsThis may seem like old news this late in the series, but way back when in the miniseries, this is the revelation that made me say, “Wow, I have to watch this show.” Knowing that the entire show would be a journey to Earth and the question of what it would be like when they got there was a compelling reason to turn in after week. It really helped the show to have an end goal in sight, and the Earth twist was a stroke of genius.2) Sharon is a CylonAlso in the miniseries, this still remains as one of the best cylon reveals to date. While about half of the Cylons turned out to be relatively minor background characters, Sharon was the first reveal of a character we actually liked, even though we had only known her a few hours. Since then she’s become an incredibly powerful force on the show in her two forms as Boomer and Athena, and has led to some of the shows other WTF moments like…3) Sharon Shoots AdamaHonestly, I’m hard pressed to think of many other times where I’ve been this shocked watching Television. When Adama went for that handshake and Sharon blasted his guts out all over CIC, I almost fell out of my chair. I mean, we knew Sharon was a Cylon all season, but the moment was completely jarring despite that fact.4) Another BattlestarMany parts of seasons 2 and 3 get kind of lost in the shuffle as the show was finding its voice and purpose, but the revelation of another Battlestar, the Pegasus, was one of season 2′s best moments. The appearance of the Pegasus led to an incredibly layered season as Adama and Cain struggled for power, it was discovered they had cannibalized their fleet and raped their Cylon prisoner, and finally the destruction of the ship during the escape of New Caprica.5) Saul Kills Ellen There were a lot of frakked up moments on New Caprica, but perhaps none of them were as bad as Saul Tigh poisoning his own wife. Ellen was feeding information to the Cylons (well, now we know why) so Saul’s hand was forced as he had to follow his own statements about doing what was necessary to help the anti-Cylon rebellion (ironic now, yes?). Sure we all hated Ellen (and wanted her to stay dead I’m guessing) but this was truly a tragic moment on the show, and one I haven’t forgotton.6) The Death of Kara ThraceStarbuck’s death remains a mystery of the show, even now with only the two hour finale ahead of us. After chasing a rogue raptor and experiening hallucinations, Starbucks Raptor exploded in front of Lee’s (and our) eyes. At the time, it really did look like she was dead (although I think most of us didn’t believe it) but the show certainly did act like it for some time.7) Final Four RevealedMost definitely one of the biggest frak moments on the list. Cylon reveals were usually painstaking ordeals, slowly unmasking them one at a time, but four of them, all at once? Insane. And not to mention most of them were characters we had all grown to love over the past three season. Newcomers like Anders and Tory weren’t as shocking, but Tyrol and Tigh? Absolutely insane at the time.8 ) Earth is Frakked UpI’m still a little disappointed with the final Earth situation upon arrival. Seeing the fleet broach Earth’s airspace was truly a majestic sight, but that was fleeting as they immediately landed in a pile of radioactive mud. Then we learned that Cylon’s had populated Earth before (so that would be…us?) and they were wiped out by nukes from the heavens, sent by…? More of Earth’s mysteries are still to be revealed in the finale. At least I would hope so.9) Starbuck Finds Her BodyThis moment was so frakked up it even freaked the seemingly all-knowing Leoben out. We saw Kara die, we saw her return, and now we see how both make sense. There are (at least) two Starbucks. We don’t know why that is, she could be a Cylon, a half Cylon, or something else entirely, but it’s certainly one of the mysteries we’re most anxious to see explained.10) Ellen Tigh: Final CylonSpeculation about the final Cylon was at beyond a fever pitch when the second half of season 4 premiered. Everyone had their guesses, charts and graphs about who it would be (mine was Billy), and I don’ t think many wanted to believe it was Ellen Tigh, one of the show’s most hated characters. But clearly it had been planned for quite some time (see Baltar’s Cylon-detector test of Ellen back in season 1), and it clearly fits into a larger picture somehow.One final thought.Is anyone else as nervous as I am at the incredibly steep hill BSG has to climb tonight in only two hours? There are an astronomical amount of questions yet to be answered, and even if they were explained purely in exposition form, I feel it would take way more than two hours to get through them all.Do you trust the show to give you a satisfying ending? I really want to say yes, but I just don’t know. This isn’t The Sopranos. They can’t just hit the lights and expect everyone to say it was “artsy.” We need answers. I just hope they can give them to us.
