I think that Mrs. Salad requested this for the Netflix queue due to the presence of Mr. Darcy himself, Colin Firth. And it's pretty funny to see Mr. Firth manage a foreign (in his case, Southern) accent. But… Well, it seems to have not to have obtained a theatrical release in the US, and did negligible business in other countries.
Based on actual events. It's set in sleepy West Memphis, Arkansas in the early 90's. It starts out with a horrific crime, the murders of three children. Suspicion quickly falls on the local weird kid and his cohorts, suspected of being Satanists.
Reese Witherspoon plays a grieving mom. Colin Firth plays a private investigator hired by the defense team. Captain Pike himself, Bruce Greenwood, plays the trial judge. That guy you've seen in dozens of things plays a cop. Mostly everyone seems kind of bored.
Here's the thing: there's not a lot of drama. No big courtroom revelations. The real-life events this movie was based on did not have a satisfactory conclusion; hence, neither did the movie.
