I've been watching the second series of Blake's 7 today. It was first broadcast in the 1970s, so the special effects and sets are a little flimsy but they are good enough to convey the stories. I love the characters, they really are the strong point. I include the computer cast in this too. One thing I noticed today but hadn't paid much attention to in the past is just how enormous the sleeves of Roj Blake's costumes are! You can see what I mean in this picture. I also ordered series 3 and 4 today, I have series 1 and 2 for several years but haven't bought the others until today. Couldn't resist. It also fits in with a little home project I'm working on - more at some point soon.
