I just finished watching the season finale. That episode was a little hard to watch, quite brutal. I think the first couple of episodes were the strongest, but overall still a good season. I can't wait to see what happens next.
As a side note, the two Australian chicks in the last few episodes were both from a local soapy called Home and Away, so it was amusing to see them both pop up here. Obviously neither of them were hired for acting ability, but people in that show spend half of their screen time in bikinis on the beach anyway, which is what matters.
