Infamous serial killers in large cities almost always attract interest for movies. I've not seen the movie but if you're terming it anti-Muslim or anti-Pakistan simply because of the location then that is wrong.It becomes a breaking news because it is less in our societies.
In the west rapes happen like everyday. lol.
Crime happens everywhere, including Islamic nations, we just generally have different ways to reduce it and respond to it. Does not mean it doesn't exist.
