This started with a very compelling plot, but faltered and failed to deliver on the last stretch of episodes, as it becomes predictable with many plot holes left open. Doesn't feel satisfactory overall.
With the final episode coming in, the fun of finding who is/are the killer/s or their motives just fizzles out quickly since the plot doesn't make sense at this point. Sucks since this drama has so much potential but the reveal just lands flat and obvious.
