It is forty years since Doctor Who fans got two big shocks with `Earthshock`. I was lucky enough not to know what was coming up in this story so I was able to be shocked indeed. Anyone who watched the episode live back then will tell you what a big impact it had- the latest DWM has some examples- and all this time later it remains one of those stories that you watch with anticipation. The edge is still there- this is not a cosy watch like for example `Revenge of the Cybermen`, it’s a thriller with bite. It wasn’t just fans who were affected by `Earthshock`. It proved to be a hugely influential story on this period of the series which turned out to be a good and a bad thing. On the positive side it’s style led to a number of subsequent stories pushing the envelope when it came to both scripts and presentation such as `Caves of Androzani,` `Revelation of the Daleks` and `Vengeance on Varos`. However it also started a trend for a more violent streak in the show which ultimately was a contributing factor to the 1985 hiatus.
