Yeah, my damned ISP severely restricts torrent traffic, so just saw it as well.
Thought it was decent - much better than the past few episoides, but still not as good as it could be. I thought this season was off to such a good start with the first couple episodes, but it's been disappointing since. Liked the polarity reference, heh....and the "warnings" given about the Doctor scenes.
Looking forward to Captain Jack's return - I really liked the character in the first season, and although that impression was diminished by Torchwood, I still think it'll be cool to have him back.
