At first this show may seem like a mix of things that we are used to seeing in teen dramas: popular kids, drugs, bullying, sexuality and of course (why not) a little bit of blood. Nothing new so far, but this show won me over because of the characters. I think it's impossible for you to watch without feeling some kind of connection with at least one of them. Each of them has their problems, their background stories are so well done that it makes you understand some of the wrong decisions they made ... And that was one of the things that made me love this series. How these characters are human. How they act stupid but are so genuinely charismatic, you forgive them for it.
The fact that among all of their personal stuff they are being threatened makes everything better. The breathtaking thriller just makes you watch episode after episode to find out what's going to happen.
It has problems - but if you watch teen shows waiting for the best script ever made, I have to say that you're doing it wrong. Some may say this show doesn't handle serious issues with care, but having in mind that shows like "13 reasons why" and "Elite" exists, I don't see nothing so bad about it.
Worth to watch.
