Some of the negative reviews seem to suggest the good reviews are a "conspiracy", unable to grasp the simple concept that we all have different tastes.
There are plot holes for sure, but the story hits you hard when you realize every character is a despicable human being, and you see the horrible cruelty, ego, and hate that fester in the human psyche. It's well acted, and the story develops impressively.
The 7/10 score reflects the plot holes, all the things that happened between Katherine and Jonathan were only witnessed by them, yet somehow the grieving mother wrote it up as if she saw every moment, and then it just became fact in the show.
But it is powerful, the emotions it instills, the wonderful way you catch yourself feeling sorry for one of the characters, only to realize they are despicable.
Well worth a watch (I am not a bot or an employee of the production company in case any conspiracy theorists are here).....(that's what THEY would say!!)
