On the one hand, I liked the premise of a zombified army of people greeting each other, as well as the twist that it’s done by a first contact protocol gone wrong and a dead alien. On the other hand, there was a lot of focus on original characters and aside from the sending of the gibberish message, Tosh and Ianto are stuck in the Hub and get little to do or shine in. Definitely suspect that it will one of the weaker audios of the series.
