Another excellent entry in the final box set of the Doctor & Valarie series. This story picks right up from where the last story ended, and features a lot of elements from the previous entries in the series. The plot is simple, but with enough things going on to really keep you on the edge of your seat. Very little is predictable, and that leads to a generally fast-paced experience. The hour really flew by. The voice cast does a magnificent job all around, with the only problem being that the Dalek voices by Nicholas Briggs sometimes sound almost like his natural speaking voice. But overall this is a minor quibble. This, what appears to be a four part story, is shaping up to be one of the best in all of Doctor Who.
