I don't really enjoy watching films about sick, twisted people. But they are sometimes interesting. This one was small, and based on writing and tension. Both of which elements were above average.
The Belfast setting was refreshing for me, since I haven't seen many films based in Northern Ireland, and the cinematography did it justice.
Both leads seemed perfectly cast. That is so important.
I don't recall any music or sex, and the violence was minimal.
The ending included some memorable imagery that I would not have predicted.
But I still wish I hadn't watched this film. Because it will just add to the endless gallery of disturbing images in my mind from past viewings of countless films. So many of which these days are about murder, infidelity, crime, or depression.
