Donna rocks my socks! And my trepidation about Rose returning, at least in this episode, was soothed. Probably because she had no scenes with the Doctor. So no mooning. Yay! And I always love alternate future type things, so this was great all around.
And next week's looks like a real zinger! The only person I didn't see was Nine. I was saying to Nin that this looks like the new series version of the classic series episode 'The Five Doctors'.
