I didn't even knew about this series but saw a somewhat high rating and gave it a try.
Honestly the production quality is superb, everything looks good, feels properly placed, the colors, camera angle and placement, music, etc.
I thought it was a bit slow at the start but decided to watch a second episode to see if the script was on par... that same day ended up watching 2 whole seasons, just keeps getting better.
It's also not very predictable, wich is a big deal since i watched too much of these series to often predict the outcome, i was thankfully mistaken on many occasions.
I won't go into details to keep the review spoiler free but if you're into suspense, manipulation and fake morals give it a try.
