according to an article i saw a short time ago, the CSA scene is going to be pretty much removed from the movie due to demands made by the young actor's family. I'm sure it will still be implied, however.
I think for me, I won't be looking to see this movie in a theatre setting, rather, I'd prefer to watch in the comfort of my own home should some parts be particularly triggering or uncomfortable.
I have heard the book is phenomenal and would love to read it. I like movies that have been made into books as it gives me a chance to read the novel afterwards and get the rest of the story
Anyways, if anyone is a bit leery of watching it I'd recommend proceeding with caution. Like Jarrad said the entire storyline isn't about CSA, its just one particular scene.
All the best,
