Honestly, it's not terrible, just a middle of the line drama. Somewhat edgy because of the more mature themes in it, but the story overall fell flat as it got more and more convoluted in the last few episodes.
PROS: Does a good initial job of building up the suspense of the mystery, good chemistry between the actors and pretty good acting overall. The MC . is pretty well rounded.
CONS: For all the building up of suspense, the payoff is lacking...especially for the question of their marriage imo. Story tended to kinda drag on towards the end and the convoluted plot was a little confusing to follow.
I think this is definitely an ok watch if you go in prepared for an intense tone and don't expect too much of the ending.
