I'm finding the first two episodes to be lacking in something. While I loved the new companion in the Snowmen and the Dalek episode, I'm finding they are missing some soul to her in the first two episodes. Their chemistry is not as good as the previous two.
The giant pumpkin planet was not even remotely explained. The parts were there but the cohesiveness was not (spelling?).
Of course I'll stick with it, it's the Doctor after all.
