I didn't hate this but didn't love it either. It took a little while to reveal that the family is not particularly "clean" when it comes to crime activity but that doesn't mean they shouldn't get justice for their lost loved one. It's kind of a mess. The head of the family, the mother, is kind of messed up, on drugs and in the head. She basically has an underage kid pose as the victim to flush out the bad guys. The kid admits to being messed up emotionally by her role in the whole thing. So it kind of makes it hard to feel sorry for the victim's family especially the mom.
Content aside, the doc is fairly fast paced and relies mostly on interviews with the Homicide detective, the victim's family and some ex gangsters, but it's mostly interviews with a few live clips and some recreations. It lays out the tale concisely and moves it along at a brisk pace, with a fairly bland conclusion in the form of text on the screen to update you "10 years later the mother becomes president of the USA and yadda yadda yadda that's the reason we now have an alien invasion happening at our Mars colony". It glosses over major events that would have been cool to have seen in clips or something.
I watched this because Netflix recommended as one of my top choices but I don't think I would recommend it. I can't think of other true crime docs to watch instead, maybe go watch CSI again. If you skip this one you won't be missing much.
