good but overlong
I agree with SPCFan927's review, this is a great series, visually stunning, an original idea beautifully designed. I especially liked the dark browns and golds, the underwater figures and use of lights to imply the alien presence.
However, it is sadly marred, like many American TV serials, by being hugely overlong. Four or five episodes would have done the trick and maintained the interest. Thus it is sad but unsurprising that a new series was not commissioned, and if done properly would not have been necessary anyway. Perhaps someone can make a 2-3 hour movie?
