When trying to retrieve Lister's guitar the boys are intercepted by an enormous ship crewed by mechanoids.
I enjoyed this one for it's themes, the humour and performances.
The plot is fairly simply and contains some interesting themes about slavery and satire on revolutionary movements. There is quite a Sparticus feel to it with the themes and when certain characters are made to fight to the death. It does a good job showing the hypocrisy of the revolutionary situations where on the surface things look to be changing for the better, when in reality the only thing that changes are those in power.
From a comedy perspective it has plenty of amusement. There are no real laugh out loud moments, but I did find myself chuckling and smiling throughout.
All performances are great as always. I especially enjoyed Chris Barrie who is the most adept at changing character and has to essential play Kryten as the episode progresses.
The visuals and effects were some of the best I've seen in the franchise.
