Kept it real
Don't remember how I discovered it, could have been BBC trailers, Radio Times, or through one of several SF Media magazines I used to subscribe to.
We were introduced to the High Frontier through the viewpoint of David Calder's character, Nathan Spring, a detective who preferred human intuition over computerised probability and thus was at odds with his colleagues, and had never been "out there" in space. The first episode saw him manoeuvred by his politically ambitious boss into the post of head of the fledgling Star Cops.
We learned about life in space from Nathan's perspective, shared his irritation at little things like having to velcro himself to a wall to get to sleep in zero-g. We watched him negotiate through a tangled jungle of political and corporate intrigues and begin to mould the the previously ridiculed Star Cops into a more effective force. And we saw him and his team solve crimes too.
Both then and now the depictions of the information technology felt real and functional; every TV is also an internet and email terminal, Nathan's pocket-sized electronic confidant Box is a suped-up uber-PDA, virtual video characters answer phones and act as personal secretaries. Re-watched after more then 10 years and the ideas still felt fresh.
