I would have rolled my eyes at the Tom Tom joke, but I might have missed a frame of DW. :p I think the joke felt a little forced, but not enough to take away from the episode.
The new Cybermen. There's something about them that gives them a slightly more terrifying presence. Something with the head, I don't know quite what it is. They look better, still like the old one's, but these are great. Even if they do have an arc reactor. :p
Also, I did catch the Alons-y.
Have you noticed that they've started using more RTD era music this last half of the series. Mostly for the "Next Time" segments. That cyber track, I really kept thinking it was going to hit the Doctor Forever segment, and then they cut/looped instead. xD
