Then needed more aliens so the conflict focus was outside the ship rather than inside. Some of the early eps were like Ice Road Truckers in space.
I still enjoyed this show but the more stargatey it got the happier I was. The idea of making it grittier and with more "real" people was a good one, just too many bland one note characters. I would have loved to have had a season 3, I think it might have gotten a whole lot more interesting.
I still have the Air ep to watch with all the added footage so I'm looking forward to that.
