Miriam, Derek, Ian, and Jenny are overachieving high school students doing everything by the book. Straight A's, sports, yearbook, band, and - when coursework allows - planning and executing elaborate murders.
Really good watch, could watch again, and can recommend.
There really aren't enough movies where the villains are the protagonist.
These are all awful characters that are also killers so it's hard to root for them. I can't tell if it is poor performance from the actors or badly written characters, but this is clearly written by someone with a love of true crimes and tactical assessment.
It is really impressive with the work put in to make the planned executions believable and how twisted the events get.
