Enjoyed it more than last year's though not as much as A Christmas Carol. All those hating on the new TARDIS interior are eating their words hopefully (ironic that the majority of that crowd are the 'wait until you see it on screen' crowd whenever someone says something negative about nu-Trek).
I'm not sure about all this mystery surrounding Clara. I really enjoy the down-to-the-basics stand alone episodes (the River Song / Melody arc nearly
had me tuning out) so I hope it doesn't over shadow everything.
