The first two episodes were good but I feel they really didn't compare to the Impossible Astronaut two-parter from last season. That one was just so good and it actually set up the season with something specific to build up to. I was kind of hoping they'd use the first 5 episodes to set up a mini story arc to send off the Ponds or something rather than stick to self-contained stories.
Also, on a semi-related note, a few days ago I ended up starting a new netflix trial account to watch a movie I couldn't find a torrent for (gotta love how they require a new email address but let you re-use the same credit card over and over again lol), and turns out Torchwood is on there. So I finally watched Children of Earth. Man, that was good. Ended up watching all five episodes in a single sitting last night.
But man,
And while on the subject, I really want the 11th to run into Jack at some point. I don't care about the other Tennant companions, but this needs to happen.
