I doubt I have watched a TV series end to end since From the Earth to The Moon' but at last a show that assumes some intelligence of it's viewers and setting and story line that leads you to want to know more.
Clever style making the most of real places, buildings and setting - so does not feel too far in the future. The NZ production (and hence I assume lower budget available than a US made series) seems to have led to more thoughtful writing and directing and probably works in its favor. It will be interesting if greater funding ahead will round off the edges.
Various levels of story it seems, so one suspects the story will actually become more complex as it goes along.
Also real-life modern NZ-English language and architectural style should add a level of interest to non-NZ audiences and so probably appeal to those looking for more thoughtful programs than most.
Could be the basis for a long running and trend setting sci-fi-ish series. Well done guys.
