Adama was the character I cared about most to the end, but he had been revealed as a crappy father, and made some very bad decisions through the series.
Lee Adama was a whiny spoiled beeyotch who needed to be shot in the head.
Kara Thrace was a hateful slut with no concept of military discipline or basic decency.
By the end, almost every character had lied, cheated, betrayed, abused someone, and/or done something colossally stupid and selfish.
It had that in common with Deadwood.
