There isn't a lot going on in this documentary, except you get a brief look into the niche culture of body building. The picture of a buff woman is alway intriguing. If they had titled this: Two Marines Kill Each Other (and one had a bad lawyer) then no one would watch this. The most important thing to learn from this documentary is never speak to the police. Always, always ask for a lawyer. If you don't have one then wait for one. That's it. A lot of things go wrong when you talk to the cops! Also, if you are in a toxic relationship then please leave and seek help. The one positive thing to note is at the end of the documentary, Sally does get out of prison and reconnects with her broken family. It's bittersweet to say the least, but it's somewhat happy. Overall it's not a bad documentary and at three episodes not a big investment.
