This show belongs in the Kids Section if Apple TV has one. Also a flashback to "veronica mars". Before I justify my low rating, I will admit that as a child I would have quite possibly enjoyed this show.
Unfortnately, from the viewing lens of an adult, the show's script is poor and lacks any form of subtlety. The consequence is that too many of the scenes feel forced and unnatural. Too much attention is given to demonstrating Heide's strong character and willfulness rather than developing any sense of intrigue or mystery around the victim. Also, the portrayal of middle school characters is not in keeping with modern day children and the values they've been taught. Perhaps, the writers relied too much on their own childhood experiences.
Finally, the most disturbing part of this show is the relationship the daughter, Heide, has with her father. Now, this might be nit-picking or even controversial but she acts more like his wife than his daughter. The boundaries in that relationship just seems a little off...
This show could easily have a worst rating but I gave it the benefit of the doubt because during my childhood, I enjoyed a very FAMILIAR show called Veronica Mars.
