The start was good but it didn't stick the landing

The plot had so much potential but I feel like too many things left unanswered. I didn't like how they wrapped the second lead' storyline at all. The main plot also started getting weaker towards the last few episodes and it felt rushed and unsatisfying at the end. It's a shame really because the idea of it was so good, the story could have been amazing if they handled it differently. I liked the cast, the acting was nice, so it made for an okay watch overall.
