This was a good episode, it was similar to the episodes where they visit an evil planet not-getting-sucked-into a black hole. But oh well. It was good and that is all I really have to say. Besides this is the second episode in a row to star someone who would later play a role in "Sherlock" we had Mycroft Holmes' actor in the previous episode and Sgt Sally Donovan in this episode. Who will be next? Stubbs? Freeman? Or Cumberbatch himself?!
