Day 389: The Ark in Space Part 4

The other thing that Holmes has brought to the series, along with new producer Philip Hinchcliffe, is horror. The series has become far more terrifying over the space of the past four episodes, in thanks due to intelligent lighting, a surprisingly effective jump scare in this episode, and a dreadfully dark idea at the heart of the monsters. The Wirrn are creatures that infect their host and then take them over, slowly destroying every last part of what makes them human both physically and mentally. It's horrible to think about, and even more horrible to witness as we see Noah, the station's leader, overcome by the Wirrn. This is all remarkably frightening, and whilst I cannot comment on what younger audiences must think of this due to this actually being the first time that I watched this story (although I can say that ratings wise, this was the highest charting single story until Voyage of the Damned came along in 2007), but I can say that as an adult this was an incredibly tense and watchable experience. Any doubts about what direction the show will go in can now be laid to rest. The script editor and producer have a strong vision for the series, we have two excellent companions in the form of Sarah Jane and Harry and above all else we have Tom Baker as the Doctor, a part he was seemingly born to play.
