It was a good episode. A bit more Clara development which is nice. I do hope they pick up some new companions as companions start to become boring when theyre only there to be a counterpart of the doctor, but when there are a few around they can alternate between being counterparts and being their own characters.
I did not like the new opening. The other openings made me think "This is a device thats travels through time and space". The cogs and spiraling clockface make me think "This is a show with a device that travels through time and space". The face in the opening was pretty good though, not as striking as Matt Smith's face in the stars but the frowning eyes make a statement.
Also poor Ser Dontos
