The secret to Blake's 7 - of which I have seen two and a half seasons, but I know the ending - is to watch it with your eyes closed. Or with your imagination turned up. Blake's 7 was a shoestring-budget 1970s British science fiction television show set in a massive oppressive galactic empire. It was cheap. Literal corrugated cardboard and painted plastic stuff. It was filmed in and around quarries and factories in the UK. Uninspiring special effects. The weather: eternally cloudy, no matter the planet. But it was more than that. It was dark and bitter. The writing was incredible. There were seriously intelligent, seriously morally ambiguous characters. Many of them died. After four seasons it ended on a massive, massive downer. The evil empire won.
I guess what I'm saying here is, make more of good television.
EDIT: Okay, so it turns out they're already remaking Blake's Seven. Very well, then. My prediction: it'll stink if and only if Paul Darrow isn't in it.
