I felt this episode was good in places, but I couldn't feel any empathy for any of the characters other than Clara and the Doctor. Actually, it wasn't just empathy. I don't have to empathise with a character to enjoy watching them. I don't have to even like them, but I do need to feel something about them one way or the other. The story did not spend enough time establishing the supporting characters, so I felt they were just there as fodder. I even thought that the actor who has just finished playing "Jeff" in Casualty was still playing "Jeff" from Casualty, but just in Doctor Who.

It was a good idea to separate Clara and the Doctor as it gave Jenna Colman and the story a chance to develop the character of Clara a bit more. I also like the strong hint at the end that she may be a little bit more than just another companion.
