It has a real Hollywood psychological thriller feel to it, which will appeal to younger generations used to scary, shocker-flashback movies with surreal, supernatural twists.
Though the main character's "dream" sequences were gripping and sometimes harrowing, they weren't too much for me to take (and I hate scary movies) nor were they at all graphic, violent or gory. Those "visions" were frightening in what they implied, and most only pieced together in my mind afterward.
There is one heck of a twist at the end in the courtroom. Critics and reviewers are saying this movie meets its stated goals: educating while gripping the audience, not being preachy or propaganda, just telling it like it is. I agree.
