Star Fleet wasn’t even called Star Fleet. If you are thinking of buying the DVD you need to search for X-Bomber. Star Fleet was the BBC name, back in the days when they would regularly change the names of things to make them less scary. Teenage Mutant HERO Turtles and the like.
I can’t buy the DVD though because I remember Star Fleet as being impossibly awesome. Looking at pictures now, of those puppets, of those sets, I know that it can’t possibly live up to my memories. And why should it? I was nine, they were using technology that has been surpassed a thousand times. Better to just remember it falsely than to face the truth. That big robot though. So cool.
