This starts off quite good and loses a bit of its own focus. Or rather gets entangled by all the teen cliches one can throw at the viewer. Not to mention all the tropes from scared person makes worst possible decision. The cliches include all those secrets a character apparently is able to withhold until the appropriate moment comes for a reveal.
Wouldn't call those things coincidences, but what do I know, right? Anyway, the beginning is strong, full of mystery and some of it can carry on, even if the focus is heavily on the teenage part of the cast (I would have loved to see more of the character played by Chad Coleman for example or someone else mature who doesn't change his or her mind every other second).
The end of season 2 is also ... horrible in all the wrong senses. I reckon they though this would get renewed ... and it didn't ... so even if you feel this deserved a better rating up to that point ... you won't be leaving this satisfied! Quite the opposite will be the case.
