Sigh.  I think it was lovely.  Capt. Jack and Capt. John.  It was a bit like good fan fic.  A little of the old, a little new; omnisexual captains meeting in the night.  It didn't hurt that Jack asked Ianto out on a date and (for some strange reason) told Gwen that he came back for her.

I'm not a big Gwen fan, but I'm sure she really whipped the gang into shape while Jack was gone.

I love the way the group works together (around) Jack.  He sort of seems like he's out of his element.

The overall feel for of the show was lighter.  Even though John is a Bad Guy, the overall tone was more witty and lighter than the first season.  That's one of the reasons why I've always like Jack on Doctor Who more than Jack on Torchwood.  On Torchwood he's morose; unhappy at his very core.  Now that he's had the chance to decide to go back to Torchwood, maybe he'll actually be happy there.

The YouTube videos I saw before the show aired really do cover many of the best scenes.  That was a bummer.

I'm looking forward to the rest of the season.  It should be fun with Martha Jones and, perhaps, another visit from Capt. John?
