This is my kind of film. I am fascinated by strange psychotic nightmares and this movie is just that. But it is also a dark comedy. While I see it mostly as a horror/thriller, there will be others who might see it as a black dramatic comedy.
But either way, it is a fascinating descent into madness. The ending caught me off guard, but what an ending! It leaves the viewer a lot to think about.
Powerful performances, a complex and detailed plot, a great script filled with dread and dashes of humor, and an eerie atmosphere make this a film worth watching.
Personally, I think that I will need to watch this several more times to pick up and understand all the subtleties that are within. But it is such a film that it will be a pleasure and not a chore so to do.
