This is a pleasant and watchable tale from Pip and Jane Baker (Space:1999), a pair who are noted for their reliable professional reputation, rather than for writing anything terribly Earth shattering. The result is a highly watchable and inoffensive script with solid research behind it, but a story which is less than the sum of its parts. The Master and new evil Time Lord the Rani make a good double act and their interaction is as enjoyable as that of the Doctor and Peri. Whatever Colin Baker did wrong in the eyes of audiences in 1985, he remains far more engaging than Sylvester MacCoy and his costume, while outrageous, is certainly eye catching and attention grabbing. His sheer energy makes him never less than entertaining to watch. This story is directed with real skill by Sarah Hellings, another example of the high quality contributions made to the series by women directors. The hostorical setting looks suprb, very authentic and gives great production quality to the story. Guest stars like Terrance Alexander add real class as well. It's a pity the plot is such a throwaway thing, because the dialog is amusing and whacky and the story holds the attention well. Overall a very good 90 minutes, just a little hollow in the middle. But I enjoyed it all the same.
