I saw this in the cinema solely because I had nothing else to do and that Ewan McGregor was in it. I had no idea what it was about. I am so glad that I watched it, because this film left me thinking for ages.

This is a thriller about a psychiatrist (which I happen to be one) trying to help a depressed & suicidal patient. The film twists unexpectedly all the time without getting bizarre. The visual effects are stunning, and the soundtrack created the eerie atmosphere which gave me creeps. The best thing about this film is that the film keeps you in suspense throughout the film, without the use of sudden loud noises, gore or scary scenes. Everything in the film seemed so every day life (to me anyway) and yet it keeps you on the edge all the time. The interspersed scenes of unrelated objects creates suspense in a way that is surreal. In the ending, I was totally surprised at that happened. I had to really think a lot to figure out what happened. Usually, when I don't understand a film, I say it is bad bad bad, but for this film, it leaves me wanting to find out more about it.

I strongly recommend anyone to watch this film!
