Terrifying Descent into Madness

Rating: 10/10 (6 December 2019)

2 hours of watching a seemingly (at the outset) normal person with a job, home, loving mother, maybe a bit of an unusual medical condition, slowly descend into complete madness and destruction.
Great visuals, well shot, I am old and not easily disturbed and I found the portrayal of psychosis so completely believable it scared the hell out of me. Masterpiece.
