I have watched all 6 episodes in the vain hope that it would get better. Unfortunately it doesn't, it starts mediocre and gets worse with each episode. The premise from the first episode was intriguing and so I tolerated the poor acting but it rapidly became a poor cousin of Lost in a soap opera setting. The underwater sequences were clearly filmed in a pool with no attempt to hide it, the cloud appeared to have been cut and pasted from another programme entirely and the plants growing from the crack seemed to be a collection of ferns from a local garden centre scattered randomly in a hole in the ground. Nil points....!
