Blake's 7 is good for a laugh.When i watched it as a kid it was one of the best sci-fi shows on english television.It shows how far things have come but i do have some genuine fond memories of it.Yeah,to be honest,i really loved it.
I knew a guy who worked on the FX for Blake's Seven - he had several cheerful tales about nearly decapitating Paul Darrow with one explosion and causing a nuclear alert at the power station they were shooting at with another. Good times.
