The problem is they've dragged out what is a relatively slim story across 5 episodes. I mean what actually happened in this episode? We found out the 456 are coming tomorrow and Gwen and Ianto rescued Jack. It's filler - fun filler but still filler. Most of the reviews were quite critical of this episode but said it picks up in tomorrow night's ep. I'd like a little more character moments a little less "things go boom" tomorrow.
