Caught the last episode only last week on UKTV - enjoyed it!
I'm not a fan of Torchwood but found this to be watchable for the reasons houghy alludes to...the tone of the writing and acting has a darker quality than I remembered from seeing previous episodes.
Although I just toe-dipped so to speak, one could "feel" the back stories of the characters through some not too shabby performances which
made the premise of the government handing over children to alien junkies seem a bit more real than the whole hocum sounds!!!
A good hours worth of escapism.
