I don’t know how you do Blake’s 7 without Avon, Blake or Servalan. To me even more than Blake, Avon was the show. If the series is to continue, I see two possible paths. Recast the leads, and I mean all the leads or go down a path where you extend the universe and examine the rebellion and how Blake influenced it.
for me the Liberator Chronicles are a good substitute for Full Cast and can be definite quality listening.I mean Jennas Story Blakes Story,Three all show the immense richness to this range
