It's the 50th anniversary special featuring the eight classic Doctors, a host of companions, the Time Lords, and the Master, and it's all fantastic. Everything about this production just hits the right spot for Doctor Who's birthday celebrations. The music and sound effects are superb. All the Doctors are on fine form with Tom Baker and Paul McGann really standing out. And there's a terrifically creepy performance from Geoffrey Beevers as the Master.
I won't go into details of the story and how all eight doctors end up drawn back to an important event on the 23rd November, 1963. However it's all masterfully done, there is nothing like a good multi-Doctor story and this is a real stand out. It even features incarnations of the first three Doctors here played by William Russell, Frazer Hines and Tim Trealor. They are trapped in some sort of Tardis time pocket so their voices are a little distorted which allows the actors some leeway in their recreation of the original actors.
As well as all this there are two CDs worth of extras which are well worth listening to. It's a tremendous package from Big Finish and it is impossible to give it less than 5 out of 5 classic Doctors. Highly recommended.
