Sorry but this does not cut it for me. When looking at a documentary to take in the turbulent Colin Baker years it is easy to dwell on the negative as this does.
There were many positives in Colin's reign too.
These should have been mentioned.
For instance Colins vision for the Doctor, he had the most inauspicious of starts strangling Peri but he wanted to get towards a more mellow, multi-layered character as he has done in the Big Finish audios. It would also have been nice to have had more on Mel. I appreciate Langford was not interested - cannot say I blame her - but the character was underdeveloped and unappreciated. Gary Russell has shown that with his books and Big finish.
