I went to the one at London Wembley yesterday, and it was absolutely superb! A real atmosphere, and a true experience!
Peter Davison did a great job presenting, and there were an array of little in-jokes from his presenting that were great fun. Getting a "text" from Sylvester McCoy mid-show, reminding us he was in The Hobbit, was a great little touch. Peter Capaldi showing up in the audience was an additionally nice touch.
The show itself was amazing. The first half seemed a lot more geared towards the RTD Era, whilst the second half more towards the Moffat Era. But anyone who enjoys the music from the show or just really, really likes Doctor Who in general would have loved this!
My personal highlights were the Last Christmas Suite, Into Darkness which was basically a Dalek suite, the Series 8 Suite, and Vale Decem which I did record as well as it was so beautifully done with a montage of all the Doctors.
