Although its earlier parts were much better than the rest but the initial set up needed more time and thoughts to be put into it. They wanted to kick start the premise quickly but they rushed things along the way. The first 5-6 episodes kept you interested about the plot and had a good amount of thriller but things slowed down significantly after that and it began to lose its attraction even when they attempted to add story-altering twists. The story itself got sloppier for no reason in the second half and the villains turned out to be underwhelming. The characters never felt like they had a good dynamic or chemistry going on, not even with the most obvious main mother-daughter or father-daughter relationship. Their lack of appeal made it hard to root for anyone. Something was missing, none of them clicked.
