"The Case of Sally Challen" (2019 release from the UK; 89 min.) takes a closer look at what happened to Sally Challen, who in 2010 killed her esrtanged husband (because he was seeing other women). She was convicted of murder the next year. Then in 2014, the UK passed the"coersive control" legislation, and based on that new law, Sally's legal team files an appeal to squash the 2011 conviction, At that point, the movie examines whether her husband in fact did exercise such "coersive control"...
Couple of comments: this is a British documentary that purports to take an objective look at what happened to Sally Challen. It doesn't take long for the documentary to reveal that it is anything but that. The documentary is here to servce as a mouthpiece of Sarah Challen's legal team, pure and simple. The outcome never seems in doubt. Whether Sally Challen was or wan't under "coersive control" I will leave uo to you to decide. But as a FILM< this documentary falls short because (i) it never feels as if it seeks to bring both sides of the arguments, and (ii)" on top of that, the documentary feels stragely distant, and in the end I never cared about any of the people that appear in the film, and for that the blame must swurely fall on the 2 British dorectors. Bottom line: I did stick it out to the very end, but I woudn't blame anyone if they didn't want to finish wataching this in its entirety.
"The Case of Sally Challen" premiered on British TV in 2019, and is now available on various streaming platforms here in the US> If you are a fan of "tru crime" documentaries, I'd suggest you check this out, with limited expectations, and then draw your own conclusion.
