It was in 3D and a made sure there was no chitting-chatting going on around us. The broadcast was almost live - there was a delay while Strax told us all to shut up and Matt Smith showed us all how to put on our 3D glasses.
The show was great though. exciting, thrilling, lots of stuff for fans and casual viewers alike and uber pleasing to see David Tennant, Billie Piper, Tom Baker's returns. What with the Night Of The Doctor that's two regenerations in one week. And the third at Christmas. Stephen Moffat you're spoiling us.
