It was not fantastic, but it was such a joy to see Peter Davison again, I don't think he got the appreciation he deserved, especially coming off the back of Tom Baker and with the troubles the series had in the 80's. But he and the 10th Doctor and so alike, and to see them in the same room brings a big smile to your face. It was nice to see a nice link back to classic Doctor Who, it was some nice tension between Tennant and Davison, and for 8 minutes it was very enjoyable, it's just a shame it did not turn out quite like i hoped. part of me wanted to see the 5th doctors TARDIS despite how silly that sounds. But still, i am happy to give this 4/5
