Note: this is a mostly spoiler-free review of Making a Murderer Season 2, which is now available to stream on Netflix. It's not often a true crime documentary becomes nationwide watercooler fodder, but that's the power of Making a Murderer. This Netflix original series arrived in 2015 and exposed millions of viewers to the tragic story of Steven Avery and his nephew Brendan Dassey, both of whom are currently serving out life sentences for the rape and murder of Teresa Halbach.
