The show doesn't exite you after watching first few episodes. It feels kinda same as always type of undercover stories, but as you get invested enough you start to feel the emotions of the characters more strongly.
It's more like a bigger movie then a episodic kind of drama.
If you can get invested enough to feel those strong emotions by strong acting and all then this show is for you.
Even the action is not always the forefront of the show, its just there to get the aftereffect of the emotions that are about to come, so its more like part of strong character development.
As I said it's all about emotions.
