In praise of the female roles in Blake's 7 and sadness at the inability of modern SciFi to have so few strong women who do anything other than provide some eye candy and romantic interest.

The real thing about Blake's 7 and Dr Who from that era was that all alien planets looked like a sandy tank-training ground in Surrey that's only a short van journey from Shepperton or White city studios and cheap for on-location filming. So it's entertaining (to me at least) that apparently Mars is exactly like that.
