It had too many threads which don't tie in together, and unrealistic premisses, like the main character being portrayed like she is a great teacher, who is also a great lover to her husband, a great neighbour, a great mother, a great treasurer of a sports club, a great house wife... like, is there anything that this woman doesn't do? One wonders when and if she ever sleeps. Real life teachers can hardly make the time to feed themselves during say exam correction weeks, even less cook every day, while also organising the finances of the local sports club and making sure that the kids have freshly washed, crispy clean sports ''sets'' every other day. Major plot hole right there and then. In real life any teens who have both parents working have either long learnt to be fairly independent, or (if they are as well off as this family is) they have a maid.Then the whole teen rave party was just a whole other show in of itself as it led literally no where any near to the main plot. The kids were really good, as the rest of the acting cast was, but this really looked like the series would suddenly stop and it would switch to Channel 4, to Skins or some other teen show. I kept waiting, however, for it to intertwine with the main plot and it never did _major loose end! I guess the kids and their shenanigans and dramas were just there to show that other stuff was happening too?! lol Also don't understand why the stranger would show herself when blackmailing people, as if anyone would do that when they can just send an email, a text or make a phone call. Another plot hole there. The show had good actors, it was entertaining, but it just wasn't smart enough. Who the murderer was- was also predictable after the 3rd or 4th episode, to me at least. It was watchable and that's that.
