In some corners of cyberspace, there exists a bit of controversy. I've stayed out of the debate, frankly, in part because I abhor certain arguments but fundamentally because I've only seen small parts of the BBC's Blake's 7. But these ardent fans insist that the shows Farscape (1999-2004) and Firefly (2002) owe a pretty huge debt to Blake's 7, stating that the properties thematically cover an awful lot of similar territory. While the issue never quite seems to rise to the level of being a copyright infringement, I think the general consensus is that they're all more alike than they are different, so maybe they feel some acknowledgement as the program's 52 episode run deserves recognition to serving to inspire the later shows.
Didn't someone once say something about imitation being the sincerest form of flattery?
Because I've only seen this one sparingly, I'm hesitant to honestly offer that much in reflection. I can say that it's a show I've always wanted to explore, but I've been unable to find it available for streaming wherein I didn't have to make some investment in another APP or 'channel' and the like. From what I can recall of my research, I've yet to find a US home video release (could be wrong on that count as I've not double checked in years), and I hate hate hate hate hate commercial interruption. (Hello, DailyMotion.com and YouTube.com: I'm talking about you!) So perhaps at some point in the future I will pony up a bit more substance.
In the meantime, let me just give the program the proper birthday/anniversary shout-out in this space. It first premiered on the BBC (in the United Kingdom) on this day back in 1978, and here's the series' premise as provided by the good folks at IMDB.com:
"A group of convicts and outcasts fight a guerrilla war against the totalitarian Terran Federation from a highly advanced alien spaceship."
