I may be a little prejudiced here. I see a model spaceship flying through the stars, and I'm pretty much instantly sold. Add on that it's not just a backdrop, but the story is actually an epic Space Opera about intergalactic war, complete with futuristic blaster/gunfights, guys in elaborate rubber masks playing aliens, and a chase through hyperspace, and you basically have a story that was written just for me. You have to try really, really hard to not make me happy with that.
But regardless, Frontier In Space is a typically intelligent, complex adventure from Malcolm Hulke, well realized by the production team, an excellent showing for both Jo and the Master, and overall one of the highlights of the Third Doctor's era.
- Besides the model shots, the location footage is excellent -- brilliantly chosen locations to give a real sense of scale. Barry Letts increased the production values and stretched the budgets to their limits during his tenure as producer, and it really pays off in this one. Frontier really is set on a grand scale.
