this movie is a delve into true insanity.
the last twenty-thirty minutes produced the worst full blown panic attack and derealization i have ever experienced in my life, and such things are a nearly daily occurrence for me.
in other words, an AMAZING psychological thriller and a delve into how psychosis can be spread like a disease to those that are mentally vulnerable, and how physical abuse can be less harmful than insidious implants by others into your own mind.
give it a chance, but i extend a warning to the mentally unstable. sit still, hold on and buckle your seatbelts.
