An episode that I sorely wanted to happen. All the strife, murder and problems had to lead to something and this was it. All the key characters finally seemed to "get it." As others have said and I've thought all along, Adema and Roslin are the heart and soul of the show, respectively. Him throwing his considerable weight behind her is both uplifting and tragic at the same time (she *is* dying).
The Sharon "choice" moment was telegraphed but done well as set up in the first season. To have it done any other way was to waste many episodes of build up and conflict. The thing that entertains me the most is that many of the events are telegraphed but the payoffs and sometimes twists are what make the show special. Joss Whedon's shows have always been about a built (read: non-blood related) family. Moore did the same thing on DS9 and he's doing it here again. They fight, they make up and it works for me.
While I see this ep and the last and transitory to the overall plot, it's fun to see what is being put together. The mythology is being fleshed out and the cylons are being made to be more mysterious and perhaps a bit more twisted than they already are - a perfect mirror to humanity, really.
Two weeks until we get some more... *sigh*
