You should go and see this film. It's one of the most disturbing things I've ever seen.
I'm told that it's based on a true story. I don't know whether that's true or not and I'm enjoying trying to work it out. If it was fiction, I think people would dismiss it as unbelievable. As fact, well, there are a lot of people in the world, and people are weirder than you think.
Sooner or later, I'll go and look the story up on the internet. For now, I'm enjoying just wondering about it. Trying to work out whether or not it's plausible. Wondering whether it could be an implausible film inspired by slightly more plausible real events. Wondering if any of the people shown in the film were real people, or whether they were all actors. Wondering at the horror of it all.
