Watched Season 4, episodes 1 to 10, which I think pretty fairly concludes the entire series if one were to ignore the last 5 minutes
The show kinda got silly with the final fives being that rag-tag bunch of dislikeable characters, but there were some excellent moments so far that I think is easily up there with the best of S1-3.
Such as episode 9&10 - that had both of the Adama's best moments so far (Lee finally manning up properly, and Bill finally breaking down completely). They were tight-paced, rich in mythology without pulling too much shit out of the ass (which they did, to a degree, but it was forgiven), and had some excellent space-action going on!
Anyway, now I'm kinda left wondering where they'll go next with the remaining 10 episodes. I guess make it clear whether or not Kara really is the final Cylon (I mean, she did technically lead them all to their doom by guiding them to radioactive barren-wasteland Earth), and what the heck is that special about the Final Five. I guess they gotta deal with the remaining Cylon models as well, and perhaps Gaius little Centaurion rebellion that he might be brewing. I was pretty pleased to see some of my earlier predictions strike true (the cylons splitting up over fundamental philosophical differences and have a little civil war), but I really underestimated just how awesome of a Cylon Cavill really was.
Top-tier Cylon right there.
