The last time that Torchwood was on, it aired for 5 days in a row, and it was better that way. Some of my friends that watched all of the last mini-series Children of Earth, in one day, said that it felt less suspenseful and a little bit boring. Which makes sense, cause there was a lot of government "what are we gonna do?" talks.
I am a bit excited because of the amount of returning cast, and I always believe in Russell T. Davies. I don't think I am going to love it as much as I love the original two seasons of Torchwood, but I am curious and happily surprised that they have found more to do with the show.
