This series is so drawn out. It would have been decent if it were boiled down to a 3 episode mini series (series 1) - yep, that's right, halved. There is so much filler. Also, I might have rated it higher if I hadn't already seen Dutch show "Bellicher". This actually feels like a remake.
It's so "paint by numbers", even down to law enforcement agencies having a peeing contest over jurisdiction. I'm sure you'll have seen this all before.
