I like episode 4! Spoilers within...
Much more like it, the first 90% of episode 3, was dire - IMO Carver was an utter let down, the camp was anti climatic, and I was just bored. A shame really, because I'd liked the first 2 episodes. This episode was right back on track - though I think I made every wrong choice there was (left Sarah, robbed Arvo and shot Rebecca)
There were a few poor moments, Nick's off camera fate the biggest one of all. And I somehow loved and loathed Jane in this episode (Luke...what were you thinking?!)
I am however, a little worried about how they're going to deal with this new threat, the baby, move on to Wellington and tie up the Crista story, all in the last episode.
Still not a patch on season 1, but much better than the last one...I actually sat at the end, and went "Oh fuuuuuuucccccccccck" as it faded to black. I dont think I've done that since season 1, episode 4!
