Once again, there's dastardly government agencies stopping at nothing to prevent public knowledge of some momentous events. In this case, the discovery of a new underwater species that could threaten the planet's ecology. Although the creature is no E.T. he does seem to befriend one youngster, who protects it at all costs, not realising it is but an infant of the species and is going to get a lot bigger  and badder This 2005 series had a lot going for it. It is family drama, sci-fi, thriller with more than a few comedic moments. The characters are believable, well acted and well photographed. The show holds the attention. Of course, as with any sci-fi show, suspension of disbelief has to be achieved. And I think it is here. Alas, the series crashed after season one, so we never get a resolution. Infuriating.. There is a general comment I feel worth making here. Many TV networks and/or film distribution companies cancel, quite arbitrarily, seemingly excellent TV series  particularly intelligent sci-fi ones. Now there may be some very good reasons for this, although the audiences are treated with utmost disdain and rarely told the reasons. This in itself is annoying. What really gets my goat is that, having cancelled the series, they then issue the thing as far as it's got, on DVD, in an obvious attempt to milk the cash cow as far as possible. For previous viewers of the series that's OK, they know what they're in for but  many of these unfinished series end on a cliffhanger. Two that come to mind immediately are "Surface", and "Odyssey 5". If you've heard good things about the series and not seen it you go and buy the blasted DVD and end up with an unresolved plot issue  it makes me very angry!! I enjoyed "Surface" immensely and didn't realise the poor characters would end up in a situation that looked totally untenable  and we'll never know what happened next. I believe that there should be a prominent notice on all such DVD issues, to the effect that the story is unfinished. Nowadays I check on TV series purchases (IMDB is an obvious excellent starting point) to find out whether a 'complete' series is really complete or not. Buyer beware.
