SICK, completely sick after watching the movie.
Well, I saw it exactly one year ago, when it was shown in Polish cinemas [there was something like 'German Films', being shown in all bigger cities in my country] Though I never remember what films are about after a month, not saying a word about one YEAR, I remember me wanting to run out of the cinema when the film started. I was really shocked. And, well, nobody told me about the atmosphere of the film, maybe that's why I felt like this described above.
If you want to go out of the cinema feeling depressed, you should watch it :)
