This is a dark brooding movie that hooked me the first time I saw it. I've enjoyed watching it a number of times ever since.
Jeremy Irons is, as Leonard Matlin indicates in his review, superb in his role. There's a great deal of darkness and certainly some degree of socially deviant behavior in the film. But it's very much the darkness that provides the drama and meaning to the story.
It's a beautifully photographed film. I thought Lena Headey was quite good in addition to being stunning. Sinead Cusack and all of the supporting cast were quite good. It is an eccentric film, but I believe it comes through as a very fine piece of film making.
It strikes me as being very underrated by the users' ratings. This is probably due in the main to the darkness of the film and its most definite lack of Hollywood style optimism. The lower ratings might also be due to what might be interpreted as a conservative message. I am not a political conservative--God forbid! However, the message that there can be unforeseen and terrible consequences from our actions is something that all of us could well profit from. Very fine movie, but certainly not for those that dislike "the bad taste of things"--or the tragedies of life.
