(If you live in town, I'd be happy to share.)
Last night I watched the first four episodes, with the cat I am housesitting. He rated them highly, as they kept me on the couch where he could sleep companionably.
The show is an absolutely fascinating tour through 20th century political philosophy and pop culture sci-fi:
A Captain Kirk-type leader (Blake, who champions freedom and sports Starsky-like puffy hair) meets 1984 (a dystopian future), on a Dr Who budget (the prison spaceship seemed to be fueled by someone pouring vinegar into baking soda).
B7's creator, Terry Nation, also created the Daleks, so it's not surprising the show has that wonderful "we made these robots out of garbage cans" feel.
However, the special effects and costumes are about as far as the humor extends. This is not goofy, good-natured sci-fi.
Blake is a rebel against a Big Brother Federation of planets--not your Star Trek Friendly Father Federation--which controls its citizens by drugging their food and water with suppressants.
He and a ragtag band of criminals escape in an alien starship, the Liberator, and--for mixed motives--engage in a guerrilla war against the Federation.

I suspect Joss Whedon was going for this morally ambiguous, gritty grain in Firefly; but he didn't succeed. That show, otherwise similar to Blakes 7, was fundamentally too romantic: you never really think in Serenity, for instance, that the good guys won't win in the end, even at a high price.
B7's far more disturbing.
Last night, after watching Blakes 7 for 3.5 hours, I dreamt about being a member of a resistance group, some of whom died, horribly, of starvation.
An odd subconscious choice, as I've been stuffed with holiday cookies and candy for four days; it came, I suppose, from the show's first episode, in which rebels fast to avoid the suppressants.
Firefly and Star Trek never gave me bad dreams.
But Blakes 7 is as if someone created a show about a group of rebels operating in the evil, alternate Star Trek universe of the "Mirror, Mirror" episode--one of that show's only ventures to the dark side.
In fact, in that episode, the "good" Kirk does encourages the "bad" Spock to lead such a rebellion:

Mirror Spock: Captain Kirk, I shall consider it.
What would that have looked like? Nothing like the optimistic, silly, gung-ho Star Trek I love; somewhat like B7.

P.S. Seems I've been writing about revolutions of various sorts lately, and I want to say that while I am interested in the arts, philosophies, and personalities involved, I am not a fan of violent revolution.
I regret, for instance, that my country didn't take the gradual route to freedom from colonial rule, like Canada did, instead of taking up arms, which left a national legacy of turning to violence as a "solution."
Of course, I speak from the privilege of safety:
if I were desperate, like Blake's compatriots, I probably would do what they do. But god spare me from tapir-eating purists.
