The fiftieth anniversary of Doctor Who has been and gone. It hardly seems possible, given how long we've all been waiting, but on Saturday, both the Eleventh Doctor and his previous tenth incarnations wielded their sonic screwdrivers together, in front of the world, in the pinnacle of an anniversary extravaganza.

Read on Whovians, and rejoice...
