Definitely a must watch. I hate how good it is, and how it makes you want to keep watching.
The director doesn't like to play by the rules, but in a good way. Unlike other T.V. shows where you hear a gun shot and they skip over to something else and make you make assumptions. This show keeps you in the dark until everything is revealed. No gun shots. No expected outcome. No expected plot twist. It simply does things right. The show walks you step by step with the story line and reveals the plot properly.
The show puts the puzzle pieces together one by one, showing you a different image every time. But overall showing you how everything is properly connected and how it makes sense.
While the show does skip to the future and the past, it does so to keeps you at the edge of your seat always wanting to know what is going to happen or what happened. However, it doesn't go over board so that you lose track of the story. Just enough to make you crave it more. And once you get that piece you have been craving, it clenches the thirst unlike other shows keeping you dissatisfied.
It is simply infuriating how well written it is and how it could mimic real life with its events. It's realistic enough that makes you believe the story, and realistic enough to make you not want to be in their shoes.
Definitely worth watching.
