I had looked to see how many episodes there were left around ep 9 but scanned down and saw a few "extras" at the bottom like season trailers and mistakenly thought they were series 2 episodes. So when I was watching the last ep of the season I had no idea it was the last ep, and there was no clue from watching it that it was. It seems to be above those kinds of conventions, like "twists" and "cliffhangers", which is consistent with what the show itself is like.
Having said all that I do enjoy the show, there is no question of me not watching series 3. I like it, I want to know where it is going. But it is fair to say it could have been a lot more than what it is. It is also fair to say that if it wasnt for the BB connection, and my hardwired caring about where its going because of that connection, I probably wouldnt care anywhere near as much.
Its like a sunday roast where the meat is a bit dry, the gravy is a bit thin and watery and you only have one potato. Im still going to eat it, and enjoy it, but there is no escaping the feeling of mild disappointment.
