yeah, it seems like it didnt get as big a screening as dr who. of course being only four series might have something to do with it.
i think in the context of its time, it was a show that a lot of us here would have loved if we were adults. i was around ten when it was on so the fact that it was sci fi intrigued me, but i dont think i ever saw one complete episode because it was on later at night. so to watch the whole lot now as an adult was very interesting.
there was one episode where Avon quickly decides he has to kill Villa to survive (he is very quick on the 'either we all die, or YOU die' rational). he isnt happy about it, but he sets about the task straight away. Villa cottons on and of course has to hide. That was brilliant acting in my opinion, Avons resolve and Villas fear.
Of course the special effects sometimes makes you laugh, which wasnt the producers intention.
