[The Following Review Contains SPOILERS!]
In all his thousands of years of life, The Doctor has seen countless wonders and horrors. He’s seen whole universes freeze and creations burn. He has seen almost everything that can be imagined and several things that can’t! To the mind of The Pope of The Roman Catholic Church, this makes The Doctor the ideal candidate for a dangerous task.
Within The Haeritucum – the secret library of blasphemous books held within The Vatican – lies a volume known as The Veritas. Literally “The Truth”. No one knows what lies in the ancient manuscript, as everyone who ever read from The Veritas committed suicide shortly thereafter.
The Pope wishes for The Doctor to read The Veritas and learn its secrets. Unfortunately, before The Doctor gets a chance to look at the manuscript, The Vatican librarians discover that the book has been translated and released upon The World Wide Web. And that is just the start of their problems…
There is little I can say about Extremis without spoiling one of the best Doctor Who episodes in recent memory. Suffice it to say that Steven Moffat is writing on-par with his better episodes like The Doctor Dances and Blink, the ensemble cast do a fantastic job and the direction by Daniel Nettheim is flawless. This episode is the new gold standard in episodes to show your friend who doesn’t want Doctor Who and is uncertain just what all the fuss is about.
