Simply. The thriller masterpiece.

Rating: 9/10 (17 February 2017)

I don't mind if James McAvoy win an Oscar next year with this role. He's simply amazing with his facial expression, his eyes focus, his breath. Each personality is demonstrated with extremely good acting skills.
The music editing is so great, the camera man did a phenomenon job to reflect the horror atmosphere since minute 1 to the last minute.
Cannot ask for more. It's worth every tiny pennies I paid for the ticket!!
