A lot of it made no sense. The writing is crap. And frankly the characters aren't all that likeable. I've seen the actors in other roles. But, here they are bland versions of themselves.
If this is what passes for good tv I'll pass. It is trite. Poorly written. Jumps back and forth, frankly it's a pain to keep up. I watched the entire series, hoping something real would happen. Nothing really did.
Bored cops. Scarred ex-journalist. There was an older British show called 'The Wrong Man's', which was far better written and the characters were just better developed.
There are many things that simply just don't add up. Watch it if you're bored. But, don't expect much.
