Is it normal that i didn't think that "a serbian film" was disturbing?

I watched the movie "A Serbian Film" a while ago because a friend of mine said it was the most fucked up thing he had ever seen and since I am pretty morbidly curious I had to look it up. Because I have only seen like a handful of horror films before I was very afraid to watch it so the first 1/3 of the movie I was constantly holding up my hand so that I could cover my eyes behind it quickly if it was getting too gross, but up until I saw the scene where the main character is fucking a girl while chopping her head off with a machete I wasn't scared anymore because it wasn't anything special in my opinion and people said it was one of the worst parts. I mean, I saw people on reaction videos who cried after they had watched it, but I didn't feel creeped out or disturbed by it at all.

Am I just a psycho or can anyone else relate?
