The summary seemed insane, and yes! that's what attracted me! In a word, I liked this drama. Or maybe more, the concept of this drama. The intriguing plot was very unique. There are a lot of twists, you really need to watch each episode until the end! Above all, watching those people watching their life was really disturbing. That corporation gives you to watch the dark side of humankind. Throughout the episode, your point of view about the protagonists changes, sometimes in a radical way. and makes you wonder : what if I knew everything about my life ? The episodes are short, but each scene gives you one piece of the truth. there are also very touching episodes. The music was nothing really special imo (i hardly noticed it) but suits the atmosphere and conveys the feelings this drama brings to you. Finally, the cast was good. Not a lot of famous actors (or at least I hardly now them) but in some kind of ways that's a good point. You can focus on the story, and all the actors are doing a great job! What I disliked : - the episodes are not connected (positive aspect of this bad point : you can miss some episodes without being lost in the next ones). - the episodes have mixed value. Imo, the two first episodes were great (the first one really amazing), but the good point of the drama (the twists) also makes you reflect a lot on what will happen, and there are less surprises. re-watch value is bad for the same reason. - I didn't understand the final episode. Nevertheless, I would recommend it. At least make the experience of the first episode! And ask yourself: do you want to re-watch your life on your TV screen?
