There's are very forward thinking concepts bought to the fore in this serial. One is the prediction of reality television about a decade before it even began. The Fear Factor-To-The-Extreme type televised violence portrayed in this show also served as a slap in the face to those who felt the shows violence had gotten out of hand. People are shown being tortured,thrown into acid baths and subjected to DNA altering experiments. It also has another concept involved of how the horror of violence can be diminished when presented as entertainment. In particular when it's used to control the legitimate media. The character of Sil is one of the most darkly comic villain in Doctor Who,with his distinctive laugh and vulgar manner. Overall one of the most telling and best produced episodes of Doctor Who.
