It's a very scary movie. It really is. Fear in a kind of mundane, everydayness. The plot is simple-simple. There's a main character. His name is Henry. He's a serial killer. But it's not a profession. He doesn't get paid for it. So he gets money from somewhere, drinks beer, argues with his buddy, plays cards, watches TV, just like any other normal person. In between, he kills, well, it's like a hobby for him, to relieve stress. In fact, one of the many philistines who look alike to each other, he is an inconspicuous fellow. He looks like the neighbor in the stairwell.
In a typical maniac movie, the murder scenes, the central action, any psychological subtext is lost behind them. In this film, the director is absolutely correct in shifting the emphasis to a simple domestic description. The murders happen quickly, they are not savored as in most slashers. It's part of being. And it turns out that the serial killer is just like us, an indistinguishable person in the crowd. And that's the scary part. In the last scene. In the form of an ordinary inconspicuous suitcase on the side of an expressway, slightly stained with something red.
