A whole secret racist society? Building someone up for three years just to tear them down at the last minute? Everyone is in on it, and again with the main characters not trusting their parents. It even included the trope of “we committed vehicular manslaughter and covered it up” and that turned into “guess what the person we hit is alive”.  
I felt bad for not always liking Chiamaka because at points her attitude was awful towards Devon and she herself seemed to have some internalized issues. Another trope that popped up and wasn’t touched again was Chiamaka possibly getting drugged at a party. Over all I was disappointed and was surprised none of the characters in the background were flushed out. It felt like it was all trauma and no resolution. 

If you liked pretty little liars you would like this. It was good and it held my attention but I called some of the twists very early on and that made it predictable to me. 
 It doesn’t live up to the “thriller” element that I was expecting
