This is an extremely good episode - neither action-filled nor ground-breaking, but excellent non-the-less. Faced with starting life with nothing but their hands and the clothes on their back, they created a frontier village. No, you can't build hdro-electricity generators within months without mines to mine the ore, smelting plants to extract copper and tools to work with. Faced with the same dilemma, I would be proud to have achieved the same in such a short space of time and I'm an engineer. We saw an alternate life for these key characters - filled with adversity, hope and achievement. This season has upped its game and, despite the continuous omission of humour that would have ensured its success in the ratings, it's still very good science fiction.
