Watched the first series and it was like too little butter over too much bread. Unless you're 5 years old the lack of a coherent storyline will drive you mental. The entire second series could have been done in one episode. Acting is fine. Effects are fine. Just the complete lack of any flow or structure to it. Dreadful. I'm a Sci-fi nutter and will watch two flies in space suits climbing up a wall. But this...? Forget it. Skip it unless you have small children who like loud dramatic music and shiny things
