I've read a few reviews that have said the series makes no sense, even after watching the whole show. I have to disagree, though the show doesn't hold your hand and reveal every question, it also has just enough, I found, to be enjoyable and suspenseful. Of course not everything is supposed to be taken literally, it's a supernatural/thriller about classism, regret and fear. These key elements are what you should be thinking over while watching, in my opinion. How do the rich elite get to where they are with little or no empathy? At only 8 episodes, the show is an easy watch and really starts ramping it up at episode 4 or so. I will agree some scenes are slow, but if that's still too long for you, maybe skip it. If not, I recommend, especially for the acting and interesting character developments.
