This series got me tangled until the end. One thing that you'll notice is that this is not definitely for stupid watchers. Clues in every episodes are everywhere!
Though every production and screenplays has its downside, this is already an upgrade for an Indonesian movie. They just really have to improve some CGIs, for example in the episode 4, where Wahyu was floating, the CGI was not really that good.
This is definitely a different side of an Indonesian series, not any typical afternoon drama or action series. But will hook you until the end especially if you're a skeptical and a person that is always keen to details.
This series is not really for stupid watchers. You will see a lot of hidden clues in every episodes where you'll see which is the nightmare and which is the opposite. This is something that you have to watch until the end to see the connection in each characters, episodes and "years" that you'll at the beginning.
