This series obviously aims on a young audience (maybe 12 - 19y old?) and as such it's decent enough. The atmosphere is rather good, the acting is not great but ah well (a bit overdramatic, feels more like a stage play) but it lacks tension.
If this series was made for an older public I'd say it fails and give it 3 stars. As it is, for youngsters, its good enough for 6 points.
