‘Murdaugh Murders’ is Netflix’s latest true-crime series

Landing on Netflix as the trial of Alex Murdaugh continues, “Murdaugh Murders: A Southern Scandal” will certainly benefit from its timeliness, but this three-part production isn’t as compelling as its subject matter. Relying almost entirely on those involved to tell the story, the project has a slapdash feel from beginning to end, and finds the younger contingent, especially, to be poor narrators of what transpired.
