Yep, I thought it was shite. So, so disappointed.
The ‘four Dots’ thing 
The show is trying to go in too many directions. Is it about gangs? Paedophile rings? Human trafficking? Covered up murders? This ‘top brass’ officer has his fingers in many pies, apparently.
Also, the young criminal guy who has been accepted into the force was arrested in season one for being involved in the capture of Arnott so how does that work? Has he assumed a fake identity?
