It seems that director James Wan is indeed who one should go to if you want to make a horror movie.
Admittedly, this is a director that, although talented, is not one I am familiar with. I have only seen three of his previous films (two of which, Mortal Kombat and The Conjuring: The Devil Made Me do it, came out earlier this year), but am able to recognize his influence on 21st century horror films, thanks to movies like Saw (2004), Insidious (2010), and Insidious: Chapter 2 (2013).
Nothing else to say
