Interesting to say the least. A very interesting and gripping film.
The two major twists that happen during the story are hard to predict and really take you back and shock you somewhat.
There is a lot of symbolism in this film and some of it is hard to decipher, although it does make you think for a while afterwards.
Some aspects of the film are unusual such as short scenes (approx 5 seconds) which have no dialogue and just vision and sound. I don't think what the director was trying to achieve with these unusual scenes was completely achieved.
The film is somewhat amateurish, but not in a bad sense at all. I quite enjoyed the silence while credits were rolling etc. It gave the film a very raw feel, which made me feel like I was watching a first edit or something, which I liked.
The acting is very good, as is the lighting and scenery. I felt Tom Wilkinson's performance was quite exceptional.
All in all a good movie which builds up to a final climax which is slightly expected, but also unexpected to an extent.
Very good viewing, I recommend it.
