A beautiful story! The Eighth Doctor and Mary Shelley meet the Cybermen, which was fantastic! I'm a big fan of the Haunting of Villa Diodati, but in so many ways this story is so much better! The Silver Turk itself is a fantastic concept, and the performance by Nicholas Briggs is chilling to the core! I adore the big twist at the end and hope we get to see the payoff someday! Mary is a brilliant companion and I love seeing her struggle with the Doctor's morals against the Cybermen. The music is brilliant as always (love this version of the title theme, wish it would be the one used for the modern 8DAs). There's some really gruesome moments which work so well and I think it's ultimately just a fantastic story! And of course, it's an Eighth Doctor vs Cyberman story, which is usually a recipe for good things!
