It will take probably just two episodes to for you to find out that the scriptwriters have absolutely no understanding of the word 'credibility'. This is the TV version of a very old British institution, the pantomime, where the audience shouting 'behind you!' is all part of the typical panto experience.
The series starts off well enough to get you interested but by episode 2, you're starting to to sniff out the unfortunate fact that the script is seriously flawed. The writers don't seem to know where to take you but keep digging the hole of confusion deeper and deeper. All the main characters come across as truly brainless and no amount of shouting 'behind you' can either save them or you, from simply switching off.
