Why not set the plot in L.A.? Why Istanbul? (SPOILER)
There doesn't seem to be any reason why they went to Istanbul, rather than Brian working there. I think it would have been more fitting to set it in L.A. In a way, it's kind of scarier to see men come from another continent to where you live, to get revenge on you, rather than waiting till you go to another country.
What do you think?
