I don't usually write reviews until I've finished the entire thing, but with this one I'm only 4 eps in but I'm thoroughly impressed and couldn't stop myself from saying something.

Incredibly realistic and relatable. Characters behave exactly how a real person would, if they encounter a situation like this, and the show doesn't shy away from showing us each an every thought process they go through which is very organic instead of having leads who are either super smart or super stupid.
However, this is exactly what makes the show difficult to watch, at least for me. Not because it's particularly gory or thriller-y but because IT'S TOO REAL! It made me feel second hand stress and panic because the characters were doing exactly what I would do and.... holy moly the impact it causes.
Therefore I would say you'll need some guts to watch this, unless you aren't particularly sensitive to that sort of thing. Me? I had to pause like every 15 mins because I was anxious watching the characters' desperation. Also the police being strict and serious with their job... and there can be very few nightmarish things to a civilian than finding yourself on the wrong side of the Police, and them not believing a word you are saying. It's no joke.
Shudders.
