Yeah, this was a great episode. Much better than last year's Christmas special, and it being in the mdidle of a season with the transition just made it work even better
I actually like the new TARDIS interior. It seems a bit small compared to the last one, similar in size to the one of the Eccleston/Tennant eras, but I'm definitely liking it.
The new title sequence is just awesome and a brilliant callback to the originals, perfect as we go into the 50th anniversary
The stuff with Clara is interesting, very interesting.
Roll on the second half of the season
