Darker and more adult themes than Doctor Who indeed. In the span of 50 minutes we got cold-blooded murder in the name of "science," use of adate rape type substance, and suicide.
I loved all the little references to Doctor Who: the Doctor's hand, Rose is the reason Jack can't die, the TARDIS is the cause of the "you can't see me" field, the Doctor can explain why Jack is immortal, and probably some more stuff that I didn't pick up on or don't remember.
I loved the wide crane shots. They were just beautiful. I also loved the feel of the Torchwood 3 set, it's a stark contrast to the now destroyed Torchwood 1 offices. Hey, I just realized something, is Torchwood Cardiff a 3 because it's on BBC3 and Torchwood London a 1 because it was first seen on BBC1?
So far no one is annoying me, although it seems that Gwen is somewhat Rose like and I do hope that I don't come to hate her like I have Rose.
Hope, hope, hope so much that Jack was not serious about the mpreg, fandom doesn't need the encouragement! Neither does fandom need the nudge that Jack may have found out he was immortal by trying to kill himself. Badly written suicidal emo!Jack fics are not something I really want to see popping up either.
So when is Ten gonna come back so Jack can make out with confront the Doctor about being left on Satellite 5?
