Great phycological thriller horror suspense and intriguing.
Brilliantly leading role played by James McAvoy.
His many personalitys are all interesting, however you know he is hiding a very dark side. His abduction of the three teenage girls and how he treats them as each personality says hello to them, only one girl wants to see who the enemy is, and how to survive, is more because she to has a dark side, she can't share with her class mates, they wouldn't understand. That saves her life. The film pulls you in because you can't predict what happens next.
One definitely to watch...
