The good news is that Moffat is doing well, and the bad news is that Moffat is doing well. What do I mean by that? I found the episode both enchanting and twisting, yet behind all that hullabaloo, predictable. That is, even the twists and turns are getting to feel familiar. That tells me that it's time for Moffat to move on. I would really like to see a new show runner along with the new Doctor. Moffat's beats are just too familiar now.
I enjoyed the new Doctor. I never had a doubt about him doing well and the actor showed me why the producers hired him. He has a grand energy. Its his energy that tells me that we new a new production team, because he's shining so much brighter than they are.
I greatly enjoyed the faces on all the extras. I do believe that they hired every actor that they could who didn't look classically pretty, giving them a wonderful age, gender, and racial range that you rarely see in any TV show.
The end of the show leaves us with questions, as it should, but I found myself not caring very much. For most of the episode, I found myself not caring very much. I was amused, but not engaged.
Themes. We have some predictable themes. First, we have the "promised land" mentioned by some robots, while the Doctor is searching for his promised land of Gallifrey. We have faces and appearances as a theme.
The audio track is far more mechanical. From the opening theme to the end, the sound of clockwork prevails.
We have a beginning where the Doctor has come back to life, and end where a robot comes back to life, and the question of what else could be coming back to life. Is that a theme or not? I don't know.
