These episodes of Torchwood were really good- a good story I mean. The problems only occurred when there were moments of dialogue unrelated to the children-are-alien-crack plot, ie whenever Ianto talks to Jack in a boyfriend-capacity his character seems to get more and more blah, and nobody cares when he dies.
I like Gwen and I like her average bloke husband, I even ended up liking Ianto's comic relief family, but Ianto and Jack together were so boring! How could a relationship ever have happened between them when Ianto had NO personality!?! Jack is also boring and very one-dimensional for a character who has supposedly broken all sci-fi boundaries or whatever...
The supporting cast and characters on the other hand are what made the five-day special very watchable, I loved the girl who was their spy on the inside, she was the best Torchwood team member. Sea-gully (Paul Copley) was great as a convincing looney, Peter Capaldi was fabulously teary as usual and Nick Farrell was, as usual, confusingly gorgeous as the slimy PM.
Anyway, it is a shame that Torchwood is over after these episodes proved that it wasn't all shite. But I think Torchwood fans probably missed the "sexy banter" and all the inbreeding going on in the office, whereas I appreciated it as a good fun piece of science fiction and felt it was at it's worse when Ianto wasn't focused on saving the Earth and instead was sighing; "Jack, will you still remember me in 1000 years? sob, cry, etc."
