As for the immortal Captain Jack, he is, ironically, now suddenly very mortal. The two things must somehow be connected, and the mystery surrounding it is certainly one worthy of the Torchwood Institute. Gwen and Jack reunite and reluctantly go back into action, this time adding CIA agent Rex (Mekhi Phifer) to sort out the "miracle" (which has several definite downsides, including a mega population boom).
Captain Jack is exactly the sort of literary hero to whom I gravitate: brilliant, outwardly brash, even egotistical, but harboring a lot of torment and secrets buried deep inside. He has a deeply human side, but can come across as cold and overly rational when weighing life and death choices. (Okay, I admit it, he's very, very easy on the eyes.) The rest of the characters in Torchwood are quite compelling in their own right; none of the characters—friend or foe—are cookie-cutter stereotypes.
Of course now that I’m hooked, I can’t stop with four seasons of Torchwood. I have to go back at least to the relevant Doctor Who episodes (with Christopher Eccleston and David Tennant as the ninth and tenth Doctors). And then of course there are the fansites, novels, and audio books. It's a good thing House doesn't come back on the air with new episodes until early October! (Oh, and there is even one episode of the very British Torchwood series that references my own favorite doctor!)
Torchwood airs Friday evening at 10 PM ET on STARZ.
