It was quite entertaining. Many of the literary elements were recognizable. For a first episode, I can see how they're setting up things for the series. The strengths, I'd say were casting and costumes. This is clearly not an accurate adaptation and it was curious some of the choices jettison were some of the more charming introductory plot elements.
Peter Capaldi's performance was chilling. I fear this will make it more difficult to win me over as a fan of his new Doctor [Who].
