I have started watching Blake’s 7, for a 1970s SF series it’s not bad. It’s special effects are slightly below Star Trek:TOS but tolerable. I find the stories to be everything from very good to so full of plot holes that you think they lost part of the script. Avon & Villa are the most interesting characters and carry the series. It is bizarre that the “hero” Roj Blake for which the series is named disappears for half its run. That’s an odd twist! Was it planned that way or the result of a contract dispute? Anyway I am mostly enjoying it.
Avon was my favorite and had great insults for the others:
