This does not feel like the natural canonical continuation from The Talons of Weng-Chiang, because Horror of Fang Rock is far more serious as it still has the Hinchcliffe feel, so I feel that Leela is very well judged but the Doctor lesser so, because the script lays on a little too heavy the dialogue style from many stories on.

The story is quite good, but not brilliant. There are nice characters although the resolution perhaps not ideal. The crew seem too keen to run away. Picking up on hints of Talons (costumes and initial time period) and Nerva (Ark and Revenge) are a good idea but perhaps underused as Nerva was a key element to season 12, so it may as well been any station.

Tom Baker sounds marginally different to the 1970s which is understandable. Relaunching the mid-4th Doctor period is comparable to the relaunch of Blake's 7. Both have been done by Big Finish recently, and I think the B7 one is better. I am more convinced it is the same people and period-fitting scripts with B7 than I am the mid-4th Doctor period.

Big Finish over the last 10 years have bettered the 5th, 6th,7th and 8th Doctor eras over their television counterparts. Following the trend with the 4th Doctor era will be tricky, perhaps impossible and setting this story between two of the best classic Who stories (Talons and Horror) only draws attention to the fact that Destination Nerva is a weaker story with the wrong era dialogue.
