I'm late, but I finally caught the first two episodes. I have notes.
1. RTD, when you crossover Torchwood and Doctor Who, please pay attention to how you do Jack's entrances/exits on each show. It's bad enough the season 1 finale of Torchwood implied the TARDIS landed in their base and picked Jack up (followed by a Who episode of Jack running outside and latching on). But now? Now you've ended an episode of Who with Jack returning to Torchwood during the day (no more than a week after leaving), and began Torchwood with Jack popping up at night after disappearing for god-only-knows-how-long!
2. Owen: "Let's all have sex."
I think in an interview, RTD once said he doesn't listen to the complaints and pleas of fans over the internet. The fact that Owen (minutes before Cardiff might explode) just randomly said he wanted to F everyone in the room is just... pathetic. And this is an episode after Owen gets an iota of characterization by telling Tosh get wants a proper girlfriend.
3. Well, at least Gwen's finally fulfilling her role as "the one with a heart."
4. Are we just randomly flipping coins each episode, when it comes to Tosh & Owen's sexualities?
5. Since when did Gwen and Jack have a thing? Sure, they've always been physically attracted to one another, but there was no relationship "thing" going on, as was implied when Gwen said she was engaged to Rhys.
6. John being attracted to a dog? Funny. That odd, ill-defined sexuality thing is always fun, when used in small doses. You know, when it's unique for one or two characters. Not the whole cast.
