The first proper story in Colin Baker era which incorporates many themes and issues – dictatorship, money, greed, and power. On the whole the production is very pleasing to look at – dark lighting, impressive sets and a lack of ambient music all make for some eerily crafted scenes. One of very few adventures in the next few years where money was well spent. Colin Baker gives one of his best performance although a crude remark after a couple of gruesome deaths does make one raises their eyebrows. Nabil Shaban clearly loves working on the show playing a surprisingly expressive, little alien with so much power in his hands. The story has a hard time getting The Doctor and Sil into one room and any supposedly history for the sequel Mindwarp does not really happen. The plot meanwhile is full of colourful characters but the story does drag out at certain points while a forced plot point of an impending invasion is squeezed in at the end. An excellent cliffhanger to part one remains as one the all-time best all thanks to incredible visuals, camerawork and editing. Some of the extras are also top notch especially the two mentally, mistreated Mad Men and Martin Jarvis is an absolute joy. A well-executed production which puts the much hated Sixth Doctor into new light. ****
