The acting game was on a good level and the obsession with Illuminati that the main character Karl had was something original. And he was an interesting figure with his addiction and etc.
But after some time, his characteristics can't keep the viewer's attention and the movie becomes kind of plain and dull. Some scenes were boring and some moments - monotone. I can't say there was many intriguing things during the movie so I wouldn't watch it a second time.
