Yeah, I agree about Sleeper. The one thing I'd liked to have seen in there more (damn, I just remembered I was going to do a side-by-side analysis of Sleeper and Adrift) was Ianto's pov, because I got the distinct impression that we were supposed to be seeing two people, Gwen and Ianto, both disagreeing with Jack's actions and attempting to call him out on them, each in the way have of dealing with Jack. And I don't think that panned out in the end. And yeah, the Lisa/Beth parallels were completely unexplored, and that was a shame. Wasted potential, every episode seems to suffer from that.
