I was disappointed after reading so many reviews describing this film a masterpiece. Frankly it was rather slow moving, and only towards the end does the tension wind up. I also thought the ending was somewhat overdone, and that there wasn't enough development of the son's character to make this really credible for me. Having said that, the cinematography is superb, and the choice of location as an almost constantly rain-soaked bleak Devon coastline in SW England provided the ideal backdrop to this dark story.
