Arrr! There be spoilerz here!
Frankly, I find myself losing faith in Adama and Roslin. I want to be sympathetic towards the rogue Cylons, but, were I a member of the Rag Tag Fleet, I would find their arguments lacking. The Cylons are responsible for the genocide of humanity, of which only fifty-thousand out of tens of billions survived. For years, they’ve been hunting the last few thousand humans across the cosmos, and now they’ve decided they were wrong and it’s okay to kiss-kiss and make up? Give me a break. Add to the fact that the top honchos are being all secretive, and even the vice-president is saying stuff don’t make sense, and I’d be flipping out too!
I absolutely don’t blame the crew of the Tyllium ship from fleeing, and I don’t know that I blame them for the death of a Cylon and two of Galactica’s Marines. The Rag Tag Fleet is falling apart, and while the hammer of the Galactica’s Marines have usually been able to hold it together, I think that hammer is on the verge of not being reliable anymore, thanks to Mr. Gaeta.
I have a hard time blaming Gaeta. He served as a mole inside Baltar’s administration, leaking information to the human resistance. For his trouble, Tigh screams at him in CIC, and he nearly got thrown out an airlock by Starbuck. Then, he’s shot in the leg by Anders, a Cylon, has his limb amputated, and then Anders gets … thrown out an airlock? Nope, a full pardon. And Tigh? Who humiliated him in front of the whole CIC crew as a Cylon lover? He’s a Cylon, too. So I have a hard time blaming Gaeta for stirring dissatisfaction within the Galactica’s crew: there’s a mutiny coming.
No wonder none of the Cylons really cares about Tyrol’s kid the way they do Athena and Helo’s: it’s not Tyrol’s. Seems Callie got it on with hot-shot fighter jockey Brendan “Hot Dog” Costanza. Sucks for Tyrol, but it’s nice to see Hot Dog get some face-time: he started off strong in the first season as a kid drafted out of the fleet to replace deceased fighter jockeys. Since then, he’s been the occasional background player with dialogue, but the last role of substance he had was of leading the Viper squadron which attacked the Cylons on New Caprica. In this episode he finds out he’s a daddy and gets his face bloodied by Tyrol: really, here’s the thing – given the nature of the fleet, and people’s feelings towards Cylons, isn’t Tyrol smart enough to realize that bashing someone’s skull in is probably not going to go any distance towards making people trust him? Guess not.
Lastly: I went back and watched the final 4.0 episode’s end. That planet doesn’t necessarily look like our Earth, or at least, you can’t tell – it’s green ,it’s blue, there are clouds, but I couldn’t make out any continent that I would point to and say “Oh, that’s Asia!” or “That’s Africa!” I think there’s some misdirection going on here, and while the planet found may indeed be their Earth, there’s nothing to stop the Colonials from finding another habitable world nearby, one with recognizable continents, and christening it Earth: our Earth.
