The rating for this show is completely off the mark. I had high expectations for the show partially because of the rating and partially from watching the first episode. However, it only took a few episodes for the constant replaying of particular scenes and extended pauses to make me want to fast forward. The suspense is lukewarm at best and the acting is probably the only thing going for it. The story was a nice change of pace from the typical rom-com but was carried out badly. The characters were very one-dimensional and predictable and there was little to no growth.
Overall: Don't recommend it unless you're into serial killer + don't mind rewatching the first episode flashback multiple times in the same episode throughout every episode. Lastly, the episodes were too short, there's no need for this show to be 32 episodes. Could have been done in 12-16 episodes with better storytelling.
