How is the movie "A Serbian Film" ?

well i heard that the movie is the most shocking and disgusting movie of the decade and im a pretty gorehound nd watched the trailer nd it looks kinda gory but i dont really want to watch it and be disappointed...and i heard the movie has something to do with a newborn baby and was wondering if this is even true or is it just rumor ???? cuz if its true thats pretty damn sick...
