It is indeed an amazing film! Saying that the film photography is 'perfect' is not enough! The story is very interesting and we can experience a very good acting from all the actors and actresses throughout the film. The fear provoked by the film is based on simple things, which in my opinion is the best, not like extravagant special affects like American or English films. This is a fine example of the power of the Portuguese film industry and very good professionalism! This is another example among many others of good cinema made in Portugal, it deserves to be seen all around the world!
About many other comments about this film...I don't agree with them obviously! Many of them were wrote for Portuguese people with small minds with the ridiculous idea of "what is Portuguese is bad", It is just sad...
Still a great film! Hope you watch it!
