If there is one thing thatNetflixis guilty of, it is the shameless overproduction of true-crime documentaries. Let’s be honest, though; the obsession with following along those stories, trying to figure out who the murderer is or why crimes were committed, is more than real, and, well, Netflix knows that. Among many others, one of the best Netflix series,Worst Roommate Ever,had viewers shocked over the specific details given by survivors, and, after its impressive success, its spinoff seriesWorst Ex Everdraws in an equal amount of attention.

Four episodes explore four different cases, diving into the details of shocking crimes and allowing those involved, as well as survivors, to recount their harrowing experiences. While, at first glance, a season with only four episodes seems far too short, the immenseweight and traumaof each episode is already so much to digest that more wouldn’t even be possible. There is no doubt that each story is beyond disturbing, but one specific mother-daughter duo inWorst Ex Evercame up with a diabolical plan and made headlines with a spine-chilling murder.
